Merge branch '100GbE-Intel-Wired-LAN-Driver-Updates-2020-10-07'

Tony Nguyen says:

====================
100GbE Intel Wired LAN Driver Updates 2020-10-07

This series contains updates to ice driver only.

Andy Shevchenko changes usage to %*phD format to print small buffer as hex
string.

Bruce removes repeated words reported by checkpatch.

Ani changes ice_info_get_dsn() to return void as it always returns
success.

Jake adds devlink reporting of fw.app.bundle_id. Moves devlink_port
structure to ice_vsi to resolve issues with cleanup. Adds additional
debug info for firmware updates.

Bixuan Cui resolves -Wpointer-to-int-cast warnings.

Dan adds additional packet type masks and checks to prevent overwriting
existing Flow Director rules.
