====================
1GbE Intel Wired LAN Driver Updates 2021-02-03

This series contains updates to igc, igb, e1000e, and e1000 drivers.

Sasha adds counting of good transmit packets and reporting of NVM version
and gPHY version in ethtool firmware version. Replaces the use of strlcpy
to the preferred strscpy. Fixes a typo that caused the wrong register to be
output. He also removes an unused function pointer, some unneeded defines,
and a non-applicable comment. All changes for igc.

Gal Hammer fixes a typo which caused the RDBAL register values to be
shown instead of TDBAL for igb.

Nick Lowe enables RSS support for i211 devices for igb.

Tom Rix fixes checkpatch warning by removing h from printk format
specifier for igb.

Kaixu Xia removes setting of a variable that is overwritten before next
use for e1000e.

Sudip Mukherjee removes an unneeded assignment for e1000.

* '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  e1000: drop unneeded assignment in e1000_set_itr()
  e1000e: remove the redundant value assignment in e1000_update_nvm_checksum_spt
  igb: remove h from printk format specifier
  igb: Enable RSS for Intel I211 Ethernet Controller
  igb: fix TDBAL register show incorrect value
  igc: Fix TDBAL register show incorrect value
  igc: Remove unused FUNC_1 mask
  igc: Remove unused local receiver mask
  igc: Prefer strscpy over strlcpy
  igc: Expose the gPHY firmware version
  igc: Expose the NVM version
  igc: Add Host Good Packets Transmitted Count
  igc: Remove MULR mask define
  igc: Remove igc_set_fw_version comment
  igc: Clean up nvm_operations structure
