Subject: [PATCH net-next 0/9][pull request] 100GbE Intel Wired LAN Driver Updates 2021-12-15

This series contains updates to ice driver only.

Jake makes changes to flash update. This includes the following:

 * a new shadow-ram region similar to NVM region but for the device shadow
   RAM contents. This is distinct from NVM region because shadow RAM is
   built up during device init and may be different from the raw NVM flash
   data.
 * refactoring of the ice_flash_pldm_image to become the main flash update
   entry point. This is simpler than having both an
   ice_devlink_flash_update and an ice_flash_pldm_image. It will make
   additions like dry-run easier in the future.
 * reducing time to read Option ROM version information.
 * adding support for firmware activation via devlink reload, when
   possible.

The major new work is the reload support, which allows activating firmware
immediately without a reboot when possible. Reload support only supports
firmware activation.

Jesse improves transmit code: utilizing newer netif_tx* API, adding some
prefetch calls, correcting expected conditions when calling ice_vsi_down(),
and utilizing __netdev_tx_sent_queue() call.

The following are changes since commit 3bc14ea0d12a57a968038f8e86e9bc2c1668ad9a:
  ethtool: always write dev in ethnl_parse_header_dev_get
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE
