Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:
====================
1GbE Intel Wired LAN Driver Updates 2020-05-19
This series contains updates to igc only.
Sasha cleans up the igc driver code that is not used or needed.
Vitaly cleans up driver code that was used to support Virtualization on
a device that is not supported by igc, so remove the dead code.
Andre renames a few macros to align with register and field names
described in the data sheet. Also adds the VLAN Priority Queue Fliter
and EType Queue Filter registers to the list of registers dumped by
igc_get_regs(). Added additional debug messages and updated return codes
for unsupported features. Refactored the VLAN priority filtering code to
move the core logic into igc_main.c. Cleaned up duplicate code and
useless code.
