7ad24ea4bf net: get rid of SET_ETHTOOL_OPS
net: get rid of SET_ETHTOOL_OPS

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
-       SET_ETHTOOL_OPS(dev, ops);
+       dev->ethtool_ops = ops;

Compile tested only, but I'd seriously wonder if this broke anything.

The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces.  These were simple transformations from
netlink_capable to netlink_ns_capable.

The Altera driver conflict was simply code removal overlapping some
void pointer cast cleanups in net-next.

2c9826243b e1000e: Restrict MDIO Slow Mode workaround to relevant parts
It has been determined that the workaround of putting the PHY into MDIO
slow mode to access the PHY id is not necessary with Lynx Point and newer
parts.  The issue that necessitated the workaround has been fixed on the
newer hardware.

We will maintains, as a last ditch attempt, the conversion to MDIO Slow
Mode in the failure branch when attempting to access the PHY id so as to
cover all contingencies.

7142a55c3c e1000e: Fix issue with link flap on 82579
Several customers have reported a link flap issue on 82579. The symptoms
are random and intermittent link losses when 82579 is connected to specific
link partners. Issue has been root caused as interoperability problem
between 82579 and at least some Broadcom PHYs in the Energy Efficient
Ethernet wake mechanism.

To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
Low Power Idle.  This solution will cause an increase of power in 100M EEE
link. It will cost additional 28mW in this specific mode.

fbb9ab10a2 e1000e: Expand workaround for 10Mb HD throughput bug
In commit 772d05c51c "e1000e: slow performance
between two 82579 connected via 10Mbit hub", a workaround was put into place
to address the overaggressive transmit behavior of 82579 parts when connecting
at 10Mbs half-duplex.

This same behavior is seen on i217 and i218 parts as well.  This patch expands
the original workaround to encompass these parts.

77e61146c6 e1000e: Workaround for dropped packets in Gig/100 speeds on 82579
This is a workaround for a HW erratum on 82579 devices.
Erratum is #23 in Intel 6 Series Chipset and Intel C200 Series Chipset
specification Update June 2013.

Problem: 82579 parts experience packet loss in Gig and 100 speeds
when interconnect between PHY and MAC is exiting K1 power saving state.
This was previously believed to only affect 1Gig speed, but has been observed
at 100Mbs also.

Workaround: Disable K1 for 82579 devices at Gig and 100 speeds.

Fix a panic that would occur in the VF if the PF driver failed or was
removed from the host kernel. In this case, the VF driver calls
i40evf_close(), but this function does nothing because the driver is in
the resetting state. Because of this, the driver doesn't free its irqs
and causes a kernel panic when it tries to disable MSI-X.

0672a09183 i40e: Redistribute queue vectors after DCB reconfiguration
The queue vectors are originally distributed among the total
number of queues that are configured for a given VSI. The number
of queues that are configured for a VSI depends on the number of
TCs that are enabled for the VSI at VSI setup/creation time.

But, the total number of queues that are configured for a VSI may
change based on change in the total number of TCs enabled as a
result of change in DCB configuration based on DCBX.

Hence, it is required for the queue vectors to be redistributed
when the total queues that are configured for a given VSI changes.

Without redistributing the vectors the queues that are configured
for the newly enabled TCs may not be able to do any Tx/Rx.

This patch removes the unnecessary ptp_tx_work item. It conflicts with

cafa1fca9d i40e: fix Timesync Tx interrupt handler code
This patch fixes the PTP Tx timestamp interrupt handler. The original
code misinterpreted the interrupt handler design. We were clearing the
ena_mask bit for the Timesync interrupts. This is done to indicate that
the interrupt will be handled in a scheduled work item (instead of
immediately) and that work item is responsible for re-enabling the
interrupts. However, the Tx timestamp was being handled immediately and
nothing was ever re-enabling it. This resulted in a single interrupt
working for the life of the driver.

This patch fixes the issue by instead clearing the bit from icr0 which
is used to indicate that the interrupt was immediately handled and can
be re-enabled right away. This patch also clears up a related issue due
to writing the PRTTSYN_STAT_0 register, which was unintentionally
clearing the cause bits for Timesync interrupts.

In addition we need to knock the VF offline so that it does not continue

to keep separate last_rx_timestamp for each Rx ring, move
last_rx_timestamp to the adapter structure.

With last_rx_timestamp inside adapter, ixgbe_ptp_rx_hwtstamp()
inline function is reduced to a single if statement so it is
no longer necessary. If statement is placed directly in
ixgbe_process_skb_fields() fixing likely/unlikely marking.

Checks for q_vector or adapter to be NULL are superfluous.

c751a3d58c e1000e: Correctly include VLAN_HLEN when changing interface MTU
When changing the interface mtu, the driver starts with a value
that doesn't include VLAN_HLEN.  Later tests in the driver
set the rx_buffer_len based on the mtu.  As a result, when
the user increases the mtu to 1504 (to support 802.1AD for example),
the driver rx_buffer_len does not change and frames longer
the 1522 bytes are rejected as too long.

Include VLAN_HLEN from the start so that an user mtu greater then
1500 bytes is correctly reflected in the driver rx_buffer_len.

This patch fixes the first/middle/last TCP flags settings which

With this change we are now configuring the CWR bit to only be set
in the first packet of a TSO, so this patch also enables TSO_ECN,
in order to advertise to the stack that we do the right thing
on the wire.

ea699569b1 ixgbevf: Add bit to mark work queue initialization
An indication of work queue initialization is needed. This is
because register accesses prior to that time can detect a removal
and attempt to schedule the watchdog task. Adding the
__IXGBEVF_WORK_INIT bit allows this to be checked and if not
set prevent the watchdog task scheduling. By checking for a
removal right after initialization, the probe can be failed
at that point without getting the watchdog task involved.

e3e3bfdd1d i40e/i40evf: fix error checking path
The commit 6494294f27 ("i40e/i40evf: Use
dma_set_mask_and_coherent") uses dma_set_mask_and_coherent() to
replace dma_set_coherent_mask() for the benefit of return error.
The conversion brings some confusion in error checking as whether
against DMA_BIT_MASK(64) or DMA_BIT_MASK(32). For one, if error is
zero, the check will be against DMA_BIT_MASK(64) twice. Fix this
error checking by binding the check to the pertinent one.

b20a774495 e1000e: Fix no connectivity when driver loaded with cable out
In commit da1e2046e5, the flow for enabling/disabling an Si errata
workaround (e1000_lv_jumbo_workaround_ich8lan) was changed to fix a problem
with iAMT connections dropping on interface down with jumbo frames set.
Part of this change was to move the function call disabling the workaround
to e1000e_down() from the e1000_setup_rctl() function.  The mechanic for
disabling of this workaround involves writing several MAC and PHY registers
back to hardware defaults.

After this commit, when the driver is loaded with the cable out, the PHY
registers are not programmed with the correct default values.  This causes
the device to be capable of transmitting packets, but is unable to recieve
them until this workaround is called.

The flow of e1000e's open code relies upon calling the above workaround to
expicitly program these registers either with jumbo frame appropriate settings
or h/w defaults on 82579 and newer hardware.

Fix this issue by adding logic to e1000_setup_rctl() that not only calls
e1000_lv_jumbo_workaround_ich8lan() when jumbo frames are set, to enable the
workaround, but also calls this function to explicitly disable the workaround
in the case that jumbo frames are not set.

====================
Intel Wired LAN Driver Updates

This series contains updates to igb, ixgbe, ixgbevf, i40e and i40evf.

Anjali provides a i40e/i40evf patch to add Energy Efficient Ethernet
Low Power Idle stats and a fix for i40e to change the string
"Side Band" to "Sideband" for consistency.

Mitch provides 2 patches for i40evf to fix if the driver encounters
an error while communicating with the PF driver, do not shut down the
admin queue unconditionally.  Add an error message when the admin
queue message never completes and fix formatting on another message
that was unnecessarily wrapped.

Mark provides a ixgbe patch and five ixgbevf patches.  Fix a possible
infinite recursion when an adapter is removed and registers all read
as all one's in ixgbe_clear_vmdq_generic() and ixgbe_clear_rar_generic().
Converts macros to static inline functions to align kernel coding standard
and prepare for adding Live Error Recovery (LER) to ixgbevf.  Change the
ethtool register test to use the normal register accessor functions and
eliminate macors used for calling register test functions to make error
exits more clear.  Checks all register reads for adapter removal by checking
the status register after any register read that returns all F's since the
status register will never return 0xFFFFFFFF unless the adapter is removed.

Jacob implements SIOCGHWTSTAMP ioctl for igb which enables user processes
to read the current hardware stamp config settings non-destructively.

Todd adds the initial register read and write for surprise removal (LER)
for igb.

Christian Engelmayer fixes an igb memory leak in the igb_get_module_eeprom()
error handling path.

Ken Ichikawa provides a fix for igb, specifically for 82575 hardware to
specify -1 to the phc_index for ethtool's get_ts_info, otherwise a wrong
value will be set to the phc_index.

Christopher Paasch fixes a null pointer dereference in igb and makes sure
to unset the HAS_MSIX flag when the driver falls back to MSI only.

b709323d24 igb: Unset IGB_FLAG_HAS_MSIX-flag when falling back to msi-only
Prior to cd14ef54d2 (igb: Change to use statically allocated array for
MSIx entries), having msix_entries different from NULL was an indicator
that MSIX is enabled.
In igb_set_interrupt_capabiliy we may fall back to MSI-only. Prior to
the above patch msix_entries was set to NULL by
igb_reset_interrupt_capability.

However, now we are checking the flag for IGB_FLAG_HAS_MSIX and so the
stack gets completly confused:

cb06d10232 igb: Fix Null-pointer dereference in igb_reset_q_vector
When igb_set_interrupt_capability() calls
igb_reset_interrupt_capability() (e.g., because CONFIG_PCI_MSI is unset),
num_q_vectors has been set but no vector has yet been allocated.

igb_reset_interrupt_capability() will then call igb_reset_q_vector,
which assumes that the vector is allocated. As this is not the case, we
are accessing a NULL-pointer.

This patch fixes it by checking that q_vector is indeed different from
NULL.

6ab5f7b298 igb: implement SIOCGHWTSTAMP ioctl
This patch adds support for the SIOCGHWTSTAMP ioctl which enables user
processes to read the current hwtstamp_config settings
non-destructively. Previously a process had to be privileged and could
only set values, it couldn't return what is currently set without
possibly overwriting the value.

This patch adds support for this new operation into igb by keeping a
shadow copy of the config in the adapter structure, which is returned
upon request.

This patch fixes flow control autonegotiation for KR/KX/K4 interfaces.
When setting up MAC link, the cached autoc value and current autoc value

This resulted in the driver ignoring and discarding flow control
negotiation changes that occur since the caching happened, as well as
when the mac was being setup.

This patch also splits the assignments for the 3 autoc variables into
their own block, and adds a comment explaining what each one means, in
order to help keep logic more straightforward while reading the code.

dc1edc67fe igb: enable VLAN stripping for VMs with i350
For i350 VLAN stripping for VMs is not enabled in the VMOLR register but in
the DVMOLR register. Making the changes accordingly. It's not necessary to
unset the E1000_VMOLR_STRVLAN bit on i350 as the hardware will simply ignore
it.

Without this change if a VLAN is configured for a VF assigned to a guest
via (i.e.)
ip link set p1p1 vf 0 vlan 10
the VLAN tag will not be stripped from packets going into the VM. Which they
should be because the VM itself is not aware of the VLAN at all.

5b346dc975 ixgbevf: Protect ixgbevf_down with __IXGBEVF_DOWN bit
The ixgbevf_down function can now prevent multiple executions by
doing test_and_set_bit on __IXGBEVF_DOWN. This did not work before
introduction of the __IXGBEVF_REMOVING bit, because of overloading
of __IXGBEVF_DOWN. Also add smp_mb__before_clear_bit call before
clearing the __IXGBEVF_DOWN bit.

2e7cfbdde8 ixgbevf: Indicate removal state explicitly
Add a bit, __IXGBEVF_REMOVING, to indicate that the module is being
removed. The __IXGBEVF_DOWN bit had been overloaded for this purpose,
but that leads to trouble. A few places now check both __IXGBEVF_DOWN
and __IXGBEVF_REMOVING.

ed19231c76 ixgbe: add ixgbe_write_pci_cfg_word with ixgbe_removed check
Inline with the current use for ixgbe_read_pci_cfg_word, create a
similar function for writing PCI config, which checks whether the
adapter has been removed first, if Live Error Recovery has been enabled.
