[PATCH net-next 0/5][pull request] 1GbE Intel Wired LAN Driver Updates 2021-03-19

[Tony Nguyen]

This series contains updates to igc and e1000e drivers.

Sasha removes unused defines in igc driver.

Jiapeng Zhong changes bool assignments from 0/1 to false/true for igc.

Wei Yongjun marks e1000e_pm_prepare() as __maybe_unused to resolve a
defined but not used warning under certain configurations.

The following are changes since commit c2ed62b9975e3e47a8b12f5fc4ed7958104b427b:
  Merge branch 'net-xps-improve-the-xps-maps-handling'
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 1GbE

Jiapeng Zhong (1):
  igc: Assign boolean values to a bool variable

Sasha Neftin (3):
  igc: Remove unused MII_CR_RESET
  igc: Remove unused MII_CR_SPEED
  igc: Remove unused MII_CR_LOOPBACK

Wei Yongjun (1):
  e1000e: Mark e1000e_pm_prepare() as __maybe_unused

[PATCH net-next 5/5] e1000e: Mark e1000e_pm_prepare() as __maybe_unused

[Tony Nguyen]

From: Wei Yongjun <weiyongjun1@huawei.com>

The function e1000e_pm_prepare() may have no callers depending
on configuration, so it must be marked __maybe_unused to avoid
harmless warning:

drivers/net/ethernet/intel/e1000e/netdev.c:6926:12:
 warning: 'e1000e_pm_prepare' defined but not used [-Wunused-function]
