867a79e37e i40e: Request PHY media event at reset time
Add the Media Not Available flag to the link event mask.  It seems
that event comes first if you have a DA cable pulled out, but there's no
follow-up event for Link Down; if you're not looking for MEDIA_NA you will
get no event, even though there's now no Link.

8c806b676d i40e: Disable link polling
Periodic link polling was added when the link events were found not to be
trustworthy.  This was the case early on, but was likely because the link
event mask was being used incorrectly.  As this has been fixed in recent
code, we can disable the link polling to lessen the AQ traffic.

7369ca8745 i40e: Make VF resets more reliable
Clear the VFLR bit immediately after triggering a reset instead of
waiting until after cleanup is complete. Make sure to trigger a reset
every time, not just if the PF is up.

These changes fix a problem where VF resets would get lost by the PF,
preventing the VF driver from initializing.

a619afe814 i40e/i40evf: Add support for bulk free in Tx cleanup
This patch enables bulk Tx clean for skbs.  In order to enable it we need
to pass the napi_budget value as that is used to determine if we are truly
running in NAPI mode or if we are simply calling the routine from netpoll
with a budget of 0.  In order to avoid adding too many more variables I
thought it best to pass the VSI directly in a fashion similar to what we do
on igb and ixgbe with the q_vector.

f2edaaaa39 i40e/i40evf: Fix handling of boolean logic in polling routines
In the polling routines for i40e and i40evf we were using bitwise operators
to avoid the side effects of the logical operators, specifically the fact
that if the first case is true with "||" we skip the second case, or if it
is false with "&&" we skip the second case.  This fixes an earlier patch
that converted the bitwise operators over to the logical operators and
instead replaces the entire thing with just an if statement since it should
be more readable what we are trying to do this way.

5c4654daf2 i40e/i40evf: Allow up to 12K bytes of data per Tx descriptor instead of 8K
From what I can tell the practical limitation on the size of the Tx data
buffer is the fact that the Tx descriptor is limited to 14 bits.  As such
we cannot use 16K as is typically used on the other Intel drivers.  However
artificially limiting ourselves to 8K can be expensive as this means that
we will consume up to 10 descriptors (1 context, 1 for header, and 9 for
payload, non-8K aligned) in a single send.

I propose that we can reduce this by increasing the maximum data for a 4K
aligned block to 12K.  We can reduce the descriptors used for a 32K aligned
block by 1 by increasing the size like this.  In addition we still have the
4K - 1 of space that is still unused.  We can use this as a bit of extra
padding when dealing with data that is not aligned to 4K.

By aligning the descriptors after the first to 4K we can improve the
efficiency of PCIe accesses as we can avoid using byte enables and can fetch
full TLP transactions after the first fetch of the buffer.  This helps to
improve PCIe efficiency.  Below is the results of testing before and after
with this patch:

Recv   Send   Send                         Utilization      Service Demand
Socket Socket Message  Elapsed             Send     Recv    Send    Recv

bytes  bytes  bytes    secs.   10^6bits/s  % S      % U     us/KB   us/KB
Before:
87380  16384  16384    10.00     33682.24  20.27    -1.00   0.592   -1.00

So the net result of this patch is that we have a small gain in throughput
due to a reduction in overhead for putting together the frame.

08ca38742b i40e: call ndo_stop() instead of dev_close() when running offline selftest
Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull more rdma updates from Doug Ledford:
 "Round two of 4.6 merge window patches.

  This is a monster pull request.  I held off on the hfi1 driver updates
  (the hfi1 driver is intimately tied to the qib driver and the new
  rdmavt software library that was created to help both of them) in my
  first pull request.  The hfi1/qib/rdmavt update is probably 90% of
  this pull request.  The hfi1 driver is being left in staging so that
  it can be fixed up in regards to the API that Al and yourself didn't
  like.  Intel has agreed to do the work, but in the meantime, this
  clears out 300+ patches in the backlog queue and brings my tree and
  their tree closer to sync.

  This also includes about 10 patches to the core and a few to mlx5 to
  create an infrastructure for configuring SRIOV ports on IB devices.
  That series includes one patch to the net core that we sent to netdev@
  and Dave Miller with each of the three revisions to the series.  We
  didn't get any response to the patch, so we took that as implicit
  approval.

  Finally, this series includes Intel's new iWARP driver for their x722
  cards.  It's not nearly the beast as the hfi1 driver.  It also has a
  linux-next merge issue, but that has been resolved and it now passes
  just fine.

a75e8005d5 i40e: queue-specific settings for interrupt moderation
For i40e driver, each vector has its own ITR register. However, there
are no concept of queue-specific settings in the driver proper. Only
global variable is used to store ITR values. That will cause problems
especially when resetting the vector. The specific ITR values could be
lost.
This patch move rx_itr_setting and tx_itr_setting to i40e_ring to store
specific ITR register for each queue.
i40e_get_coalesce and i40e_set_coalesce are also modified accordingly to

2d37490b82 i40e/i40evf: Rewrite logic for 8 descriptor per packet check
This patch is meant to rewrite the logic for how we determine if we can
transmit the frame or if it needs to be linearized.

The previous code for this function was using a mix of division and modulus
division as a part of computing if we need to take the slow path.  Instead
I have replaced this by simply working with a sliding window which will
tell us if the frame would be capable of causing a single packet to span
several descriptors.

The logic for the scan is fairly simple.  If any given group of 6 fragments
is less than gso_size - 1 then it is possible for us to have one byte
coming out of the first fragment, 6 fragments, and one or more bytes coming
out of the last fragment.  This gives us a total of 8 fragments
which exceeds what we can allow so we send such frames to be linearized.

Arguably the use of modulus might be more exact as the approach I propose
may generate some false positives.  However the likelihood of us taking much
of a hit for those false positives is fairly low, and I would rather not
add more overhead in the case where we are receiving a frame composed of 4K
pages.

b96b78f2b7 i40e/i40evf: Replace header pointers with unions of pointers in Tx checksum path
The Tx checksum path was maintaining a set of 3 pointers and two lengths in
order to prepare the packet for being checksummed.  The thing is we only
really needed 2 pointers, and the lengths that were being maintained can
easily be computed.

As such we can replace the IPv4 and IPv6 header pointers with one single
union that represents both, or a generic pointer to the start of the
network header.  For the L4 headers we can do the same with TCP and a
generic pointer to the start of the transport header.  The length of the
TCP header is obtained by simply multiplying doff by 4, and the network
header length can be obtained by subtracting the network header pointer
from the transport header pointer.

While I was at it I renamed l4_hdr to l4_proto to make it a bit more clear
and less likely to be confused with l4.hdr which is the transport header
pointer.

This patch goes through and pulls all of the spots where we were updating
either the TCP or IP checksums in the TSO and checksum path into the TSO
function.  The general idea here is that we should only be updating the
header after we verify we have completed a skb_cow_head check to verify the
head is writable.

One other advantage to doing this is that it makes things much more
obvious.  For example, in the case of IPv6 there was one spot where the
offset of the IPv4 header checksum was being updated which is obviously
incorrect.

c49a7bc330 i40e/i40evf: Factor out L4 header and checksum from L3 bits in TSO path
This patch makes it so that the L4 header offsets and such can be ignored
when dealing with the L3 checksum and length update.  This is done making
use of two things.

First we can just use the offset from the L4 header to the start of the
packet to determine the L4 offset, and from that we can then make use of
the data offset to determine the full length of the headers.

As far as adjusting the checksum to remove the length we can simply add the
inverse of the length instead of having to recompute the entire
pseudo-header without the length.  In the case of an IPv6 header this
should be significantly cheaper since we can make use of a value we already
needed instead of having to read the source and destination address out of
the packet.

a9c9a81f58 i40e/i40evf: Drop outer checksum offload that was not requested
The i40e and i40evf drivers contained code for inserting an outer checksum
on UDP tunnels.  The issue however is that the upper levels of the stack
never requested such an offload and it results in possible errors.

In addition the same logic was being applied to the Rx side where it was
attempting to validate the outer checksum, but the logic there was
incorrect in that it was testing for the resultant sum to be equal to the
header checksum instead of being equal to 0.

Since this code is so massively flawed, and doing things that we didn't ask
for it to do I am just dropping it, and will bring it back later to use as
an offload for SKB_GSO_UDP_TUNNEL_CSUM which can make use of such a
feature.

As far as the Rx feature I am dropping it completely since it would need to
be massively expanded and applied to IPv4 and IPv6 checksums for all parts,
not just the one that supports Tx checksum offload for the outer.

73b03f9848 i40e: clean event descriptor before use
In one obscure corner case, it was possible to clear the NVM update wait
flag when no update_done message was actually received.  This patch
cleans the event descriptor before use, and moves the opcode check to
where it won't get done if there was no event to clean.

Also update copyright year in file headers.

a16ae2d59c i40e: Do not disable queues in the Legacy/MSI Interrupt handler
The queues should never be enabled/disabled in the interrupt handler,
ICR0 interrupt enable should be the only thing that needs to be
dynamically changed in the handler.

This patch fixes that. Without this patch X722 platforms were
seeing weird ping timings when in Legacy mode since it takes
a whole lot of time for the HW/FW to re-enable queues.

16fd08b859 i40e/i40evf: avoid atomics
In the case where we have a page fully used by receive data, we need to
release the page fully to the stack. Instead of calling get_page (which
increments the page count) followed by free_page (which decrements the
page count), just donate our reference to the stack. Although this
donation is not tax deductible, it does allow us to avoid two very
expensive atomic operations that reverse each other.

6784ed5a73 i40e: Fix PROMISC mode for Multi-function per port (MFP) devices
This patch falls back to enabling unicast, multicast and
broadcast promiscuous mode when the driver must disable it's use
of "default port" aka defport mode (which is normally used to
provide a promiscuous mode), due to internal incompatibility
with Multiple Function per Port (aka MFP).

The situation that requires this patch is when Physical
Function 0 is the device being used, and it can support SR-IOV
when MFP is enabled, via the driver creating a VEB on an MFP
enabled adapter.

dd353109e4 i40e: Add a SW workaround for lost interrupts
This patch adds a workaround for cases where we might have
interrupts that got lost but WB happened.
If that happens without this patch we will see a tx_timeout.
To work around it, this patch goes ahead and reschedules NAPI
in that situation, if NAPI is not already scheduled.
We also add a counter in ethtool to keep track of when
we detect a case of tx_lost_interrupt.

Note: napi_reschedule() can be safely called from process/service_task
context and is done in other drivers as well without an issue.

we need it again. Only free and reallocate pages if the count shows that
both half-pages are in use. Add counters to track reallocations and page
reuse.

This is the "Don't Give Up" patch.  Previously the
driver could fail an allocation, and then possibly stall

With this patch, the driver will keep polling trying to allocate
receive buffers until it succeeds.  This should keep all receive
queues running even in the face of memory pressure.

it to be decided by the caller whether the CLEARPBA (clear pending
events) bit will be set while re-enabling the interrupt.

ecc6a239e8 i40e: Refactor force_wb and WB_ON_ITR functionality code
Now that the Force-WriteBack functionality in X710/XL710 devices
has been moved out of the clean routine and into the service task,
we need to make sure WriteBack-On-ITR is separated out since it
is still called from clean.

In the X722 devices, Force-WriteBack implies WriteBack-On-ITR but
without the interrupt, which put the driver into a missed
interrupt scenario and a potential tx-timeout report.

With this patch, we break the two functions out, and call the
appropriate ones at the right place. This will avoid creating missed
interrupt like scenarios for X722 devices.

Also update copyright year in file headers.

With the latest firmware, statistics gathering can now be enabled and
disabled in the HW switch, so we need to add a parameter to allow the
driver to set it as desired.  At the same time, the L2 cloud filtering
parameter has been removed as it was never used.

Older drivers working with the newer firmware and newer drivers working
with older firmware will not run into problems with these bits as the
defaults are reasonable and there is no overlap in the bit definitions.
Also, newer drivers will be forced to update because of the change in
function call parameters, a reminder that the functionality exists.

when called by the team driver under rcu_read_lock(), which cannot
be held while sleeping.  Found with lockdep.

Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2016-02-16

This series contains updates to i40e/i40evf only.

Shannon adds flags to MAC allocation requests to signify that the MAC VLAN
filters should come from the shared resource pool.  Added a new "set switch
config" admin queue command and the new Cisco VXLAN-GPE cloud tunnel type
for the admin queue commands.  Added more detail to the NVM update debug
message in order to see the full ethtool request data.  Also added a few
more bits of netdev data into the debugfs output for dump VSI.

Pandi fixes the width of two datatypes which were being declared a different
size from what they are assigned.

Anjali fixes an issue where we were not doing write-back on interrupt
throttle for legacy case in x722.

Mitch adds a counter for ARQ overflows since sometimes an ever-growing
number indicates that something bad is happening.  Also added 20G speed for
Tx bandwidth calculations.

Jesse refactors the DCB function based on a community suggestion to change
the multi-level if statement into a switch statement.  Cleans up VF device
IDs in the PF, since it does not need to know them.

16e5cc6471 net: rework setup_tc ndo op to consume general tc operand
This patch updates setup_tc so we can pass additional parameters into
the ndo op in a generic way. To do this we provide structured union
and type flag.

This lets each classifier and qdisc provide its own set of attributes
without having to add new ndo ops or grow the signature of the
callback.

e4c6734eaa net: rework ndo tc op to consume additional qdisc handle parameter
The ndo_setup_tc() op was added to support drivers offloading tx
qdiscs however only support for mqprio was ever added. So we
only ever added support for passing the number of traffic classes
to the driver.

This patch generalizes the ndo_setup_tc op so that a handle can
be provided to indicate if the offload is for ingress or egress
or potentially even child qdiscs.

6e35c04cf6 i40e/i40evf: Fix RSS rx-flow-hash configuration through ethtool
This patch fixes the Hash PCTYPE enable for X722 since it supports
a broader selection of PCTYPES for TCP and UDP.

This patch also fixes a bug in XL710, X710, X722 support for RSS,
as of now we cannot reduce the (4)tuple for RSS for TCP/IPv4/IPV6 or
UDP/IPv4/IPv6 packets since this requires a product feature change
that comes in a later release.

A VF should never be allowed to change the tuples for RSS for any
PCTYPE since that's a global setting for the device in case of i40e
devices.

857942fd1a i40e: Fix Rx hash reported to the stack by our driver
If the driver calls skb_set_hash even with a zero hash, that
indicates to the stack that the hash calculation is offloaded
in hardware. So the Stack doesn't do a SW hash which is required
for load balancing if the user decides to turn of rx-hashing
on our device.

This patch fixes the path so that we do not call skb_set_hash
if the feature is disabled.

b499ffb0a2 i40e: Look up MAC address in Open Firmware or IDPROM
This is the i40e equivalent of commit c762dff24c ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").

As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.

In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.

The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.

When VFs are being reset, there is a brief window of time when they
cannot be configured because they don't have a VSI to configure. If
a script is quick, it can fall through that window. To avoid
defenestration, log a useful error message and return -EAGAIN.
