[net-next 00/14][pull request] Intel Wired LAN Driver Updates 2019-02-05

[Jeff Kirsher]

This series contains updates to igc, e1000e, ixgbe, fm10k and driver
documentation.

Kai-Heng Feng fixes an e1000e issue where the Wake-On-LAN settings where
being set incorrectly during a system suspend.

Sasha addresses community feedback on the igc driver and provides a
number of code cleanups to remove either unreachable or unused code.  In
addition, added basic ethtool support for the igc driver.

Mike Rapoport fixes the formatting of the kernel driver documentation so
that the title is properly formatted and does not get lumped with the
document sections in the HTML kernel documents generated.

Jiri Kosina updates a hard coded RAR entries value with the existing
define IXGBE_82599_RAR_ENTRIES.

Jake fixes up whitespace in the fm10k driver.

Konstantin Khlebnikov fixes an issue where in some cases, the e1000e
driver will continually reset during a system boot because the watchdog
task sees items in the transmit buffer but the carrier is off (trying to
establish link) causing the device reset to flush the buffer.  To
resolve, just move this check/flush into the watchdog section for when
the carrier is off.

Todd bumps the igb driver version to reflect the recent driver changes.

The following are changes since commit bf2fa12593c2bb77c7ab84254ac69af429d6719b:

[net-next 01/14] e1000e: Exclude device from suspend direct complete optimization

[Jeff Kirsher]

From: Kai-Heng Feng <kai.heng.feng@canonical.com>

e1000e sets different WoL settings in system suspend callback and
runtime suspend callback.

The suspend direct complete optimization leaves e1000e in runtime
suspended state with wrong WoL setting during system suspend.

To fix this, we need to disable suspend direct complete optimization to
let e1000e always use suspend callback to set correct WoL during system
suspend.

[net-next 03/14] docs/networking: fix formatting of Intel drivers documentation

[Jeff Kirsher]

From: Mike Rapoport <rppt@linux.ibm.com>

The documentation of Intel drivers is missing the heading adornment for
document titles.

This causes the generated html to have TOC entries from these documents to
appear as top level TOC entries:

* Linux* Base Driver for Intel(R) Ethernet Network Connection
* Contents
* Identifying Your Adapter
* Command Line Parameters
  * AutoNeg
  * Duplex
  ...

Add overline heading adornment to document titles.

[net-next 07/14] e1000e: fix a missing check for return value

[Jeff Kirsher]

The change is based on the issue found by Kangjie Lu <kjlu@umn.edu> where
we not checking the return value of a register read/write which could result
in a NULL pointer dereference if the read/write fails.

Since we are only trying to disable the far-end loopback, if the read
and write of register fails, we do not want to bail out of the function.
We just want to log that it failed to disable and continue on.

[net-next 10/14] e1000e: fix cyclic resets at link up with active tx

[Jeff Kirsher]

From: Konstantin Khlebnikov <khlebnikov@yandex-team.ru>

I'm seeing series of e1000e resets (sometimes endless) at system boot
if something generates tx traffic at this time. In my case this is
netconsole who sends message "e1000e 0000:02:00.0: Some CPU C-states
have been disabled in order to enable jumbo frames" from e1000e itself.
As result e1000_watchdog_task sees used tx buffer while carrier is off
and start this reset cycle again.

This patch flushes tx buffers only once when carrier is off
rather than at each watchdog iteration.
