Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
100GbE Intel Wired LAN Driver Updates 2021-02-05

This series contains updates to ice driver only.

Jake adds adds reporting of timeout length during devlink flash and
implements support to report devlink info regarding the version of
firmware that is stored (downloaded) to the device, but is not yet active.
ice_devlink_info_get will report "stored" versions when there is no
pending flash update. Version info includes the UNDI Option ROM, the
Netlist module, and the fw.bundle_id.

Gustavo A. R. Silva replaces a one-element array to flexible-array
member.

Bruce utilizes flex_array_size() helper and removes dead code on a check
for a condition that can't occur.

v2:
* removed security revision implementation, and re-ordered patches to
account for this removal
* squashed patches implementing ice_read_flash_module to avoid patches
refactoring the implementation of a previous patch in the series
* modify ice_devlink_info_get to always report "stored" versions instead
of only reporting them when a pending flash update is ready.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: remove dead code
  ice: use flex_array_size where possible
  ice: Replace one-element array with flexible-array member
  ice: display stored UNDI firmware version via devlink info
  ice: display stored netlist versions via devlink info
  ice: display some stored NVM versions via devlink info
  ice: introduce function for reading from flash modules
  ice: cache NVM module bank information
  ice: introduce context struct for info report
  ice: create flash_info structure and separate NVM version
  ice: report timeout length for erasing during devlink flash
