Subject: [net-next 00/17][pull request] 1GbE Intel Wired LAN Driver Updates 2020-05-22

This series contains updates to e1000e, igc and igb.

Many of the patches in this series are fixes, but many of the igc fixes
are based on the recent filter rule handling Andre has been working,
which will not backport to earlier/stable kernels.  The remaining fixes
for e1000e and igb have CC'd stable where applicable.

Andre continue with his refactoring of the filter rule code to help with
reducing the complexity, in multiple patches.  Fix the inconsistent size
of a struct field.  Fixed an issue where filter rules stay active in the
hardware, even after it was deleted, so make sure to disable the filter
rule before deleting.  Fixed an issue with NFC rules which were dropping
valid multicast MAC address.  Fixed how the NFC rules are restored after
the NIC is reset or brought up, so that they are restored in the same order
they were initially setup in.  Fix a potential memory leak when the
driver is unloaded and the NFC rules are not flushed from memory
properly.  Fixed how NFC rule validation handles when a request to
overwrite an existing rule.  Changed the locking around the NFC rule API
calls from spin_locks to mutex locks to avoid unnecessary busy waiting
on lock contention.

Sasha clean up more unused code in the igc driver.

Kai-Heng Feng from Canonical provides three fixes, first has igb report
the speed and duplex as unknown when in runtime suspend.  Fixed e1000e
to pass up the error when disabling ULP mode.  Fixed e1000e performance
by disabling TSO by default for certain MACs.

Vitaly disables S0ix entry and exit flows for ME systems.

The following are changes since commit 593532668f635d19d207510e0fbb5c2250f56b6f:
  Revert "net: mvneta: speed down the PHY, if WoL used, to save energy"
