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.

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.

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
Size Size Size Time Throughput local remote local remote
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
After:
87380 16384 16384 10.00 34204.08 20.54 -1.00 0.590 -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.

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

10GbE Intel Wired LAN Driver Updates 2016-04-04
This series contains updates to ixgbe and ixgbevf.
Pavel Tikhomirov fixes a typo where we were incrementing transmit stats
instead of receive stats on the receive side.
Emil updates the ixgbevf driver to use bit operations for setting and
checking the adapter state.
Chas Williams adds the new NDO trust feature check so that the VF guest
has the ability to set the unicast address of the interface, if it is a
trusted VF.
Alex cleans up the driver to that the only time we add a PF entry to the
VLVF is either for VLAN 0 or if the PF has requested a VLAN that a VF
is already using. Also adds support for generic transmit checksums,
giving the added advantage is that we can support inner checksum offloads
for tunnels and MPLS while still being able to transparently insert
VLAN tags. Lastly, changed ixgbe so that we can use the ethtool
rx-vlan-filter flag to toggle receive VLAN filtering on and off.
Mark cleans up the ixgbe driver by making all op structures that do not
change constants. Also fixed flow control for Xeon D KR backplanes, since
we cannot use auto-negotiation to determine the mode, we have to use
whatever the user configured.
Sowmini Varadhan updates ixgbe to use eth_platform_get_mac_address()
instead of the arch specific solution that was added by a previous
commit.
Don fixed an issue where it was possible that a system reset could occur
when we were holding the SWFW semaphore lock, which the next time the
driver loaded would see it incorrectly as locked.
v2: updated patch 8 of the series to include a minor flags issue where
we had lost NETIF_F_HW_TC and we were setting NETIF_F_SCTP_CRC in
two different areas, when we only needed/wanted it in one spot.

It is possible on some HW that a system reset could occur when we are
holding the SWFW semaphore lock. So next time the driver was loaded we
would see it incorrectly as locked. This patch will recover from that state
by: Attempting to acquire the semaphore and then regardless of whether or
not it was acquire we immediately release it. This will force us into
a known good state.

This patch adds support for generic Tx checksums to the ixgbevf driver. It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.
In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
MACLEN (maximum of 127), retrieved from:
skb_network_offset()
IPLEN (maximum of 511), retrieved from:
skb_checksum_start_offset() - skb_network_offset()
TUCMD.L4T indicates offset and if checksum or crc32c, based on:
skb->csum_offset
The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.
I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers. In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

DMA behavior is linked to descriptor management:
-descriptor mechanism (Tx for example, but it is exactly the same for RX):
-useful registers:
-DMA_CH#_TxDesc_Ring_Len: length of transmit descriptor ring
-DMA_CH#_TxDesc_List_Address: start address of the ring
-DMA_CH#_TxDesc_Tail_Pointer: address of the last
descriptor to send + 1.
-DMA_CH#_TxDesc_Current_App_TxDesc: address of the current
descriptor
-The descriptor Tail Pointer register contains the pointer to the
descriptor address (N). The base address and the current
descriptor decide the address of the current descriptor that the
DMA can process. The descriptors up to one location less than the
one indicated by the descriptor tail pointer (N-1) are owned by
the DMA. The DMA continues to process the descriptors until the
following condition occurs:
"current descriptor pointer == Descriptor Tail pointer"
Then the DMA goes into suspend mode. The application must perform
a write to descriptor tail pointer register and update the tail
pointer to have the following condition and to start a new transfer:
"current descriptor pointer < Descriptor tail pointer"
The DMA automatically wraps around the base address when the end
of ring is reached.
Up to 8 DMA could be use but currently we only use one (channel0)

After enabling per-cpu processing it appeared that under heavy load
changing MTU can result in blocking all port's interrupts and
transmitting data is not possible after the change.
This commit fixes above issue by disabling percpu interrupts for the
time, when TXQs and RXQs are reconfigured.

Initially the phy_bus_name was added to manipulate the
driver name but it was recently just used to manage the
fixed-link and then to take some decision at run-time.
So the patch uses the is_pseudo_fixed_link and removes
the phy_bus_name variable not necessary anymore.
The driver can manage the mdio registration by using phy-handle,
dwmac-mdio and own parameter e.g. snps,phy-addr.
This patch takes care about all these possible configurations
and fixes the mdio registration in case of there is a real
transceiver or a switch (that needs to be managed by using
fixed-link).

Intel Wired LAN Driver Updates 2016-03-29
This series contains fixes to ixgbe and ixgbevf.
Tushar fixes an issue which was introduced with an earlier commit, where
hardware register RAR0 default MAC address does not get set properly.
Alex fixes two issues, first being the VXLAN port number should be stored
in network order instead of in host order. The second fix corrects the ATR
code to handle IPv6 extension headers. The issue was ATR code was assuming
that it would be able to use tcp_hdr for every TCP frame that came through,
but that is not the case, which resulted in bad filters being setup.
Mark fixes a use of usleep_range() to udelay() in the case where a lock
is being held.
Stefan fixes the offline self tests where ndo_stop() should be used instead
of ndo_close(), which causes IFF_UP to be cleared and interface routes get
removed.
Emil fixes the error case where we need to return an error when a MAC
address change is rejected by the PF. This helps prevent the user from
modifying the MAC address when the operation is not permitted.
Sridhar provides three fixes for ixgbe, all dealing with traffic class
offload handling.

The ATR code was assuming that it would be able to use tcp_hdr for
every TCP frame that came through. However this isn't the case as it
is possible for a frame to arrive that is TCP but sent through something
like a raw socket. As a result the driver was setting up bad filters in
which tcp_hdr was really pointing to the network header so the data was
all invalid.
In order to correct this I have added a bit of parsing logic that will
determine the TCP header location based off of the network header and
either the offset in the case of the IPv4 header, or a walk through the
IPv6 extension headers until it encounters the header that indicates
IPPROTO_TCP. In addition I have added checks to verify that the lowest
protocol provided is recognized as IPv4 or IPv6 to help mitigate raw
sockets using ETH_P_ALL from having ATR applied to them.

The VXLAN port number should be stored in network order instead of in host
order as it is accessed from the hot-path in ATR. This way we can avoid
having to do any byte swaps in order to validate the port number.
I moved the vxlan_port value into a hole in the read-mostly region of the
adapter struct. This way it should be in a warm cache-line instead of in
some isolated region in memory when it needs to be accessed.
In addition I went through and stripped a bunch of unneeded ifdef flags
since having an extra variable present doesn't really hurt anything and
makes the code easier to read. I also went through and dropped the
NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides
no value as the flag is not evaluated in the Rx path.

skb_len needs to be skb_headlen(skb) in bcmgenet_xmit_single().
Fragmented skbs can have only Ethernet + IP + TCP headers (14+20+20=54 bytes)
in the linear buffer, followed by the rest in fragments. Bumping skb_len to
ETH_ZLEN would be incorrect for this case, as it would introduce garbage
between TCP header and the fragment data.
This also works with regular/non-fragmented small packets < ETH_ZLEN bytes.

1. Add bytes_compl local variable to __bcmgenet_tx_reclaim() to collect

2. When bcmgenet device uses Tx checksum offload, each transmitted skb
gets an extra 64-byte header prepended to it. Before this header is
prepended to the skb, we need to save the skb "wire" length in
GENET_CB(skb)->bytes_sent, so that proper Tx bytes accounting can
be done in __bcmgenet_tx_reclaim().
3. skb->len covers the entire length of skb, whether it is linear or
fragmented. Thus, when we clean the fragments, do not increase
transmitted bytes.

- A few minor core fixups needed for the next patch series
- The IB SRIOV series. This has bounced around for several versions.
Of note is the fact that the first patch in this series effects
the net core. It was directed to netdev and DaveM for each iteration
of the series (three versions total). Dave did not object, but did
not respond either. I've taken this as permission to move forward
with the series.
- The new Intel X722 iWARP driver
- A huge set of updates to the Intel hfi1 driver. Of particular interest
here is that we have left the driver in staging since it still has an
API that people object to. Intel is working on a fix, but getting
these patches in now helps keep me sane as the upstream and Intel's
trees were over 300 patches apart.

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.
Summary:
- A few minor core fixups needed for the next patch series
- The IB SRIOV series. This has bounced around for several versions.
Of note is the fact that the first patch in this series effects the
net core. It was directed to netdev and DaveM for each iteration

The driver calls gpiod_set_value() with GPIOD_OUT_* instead of 0 and 1, as
a result the PHY isn't really put back into reset state in macb_remove().
Moreover, the driver assumes that something else has set the GPIO direction
to output, so if it has not, the PHY may not be taken out of reset in
macb_probe() either...
