Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue
Tony Nguyen says:
====================
Intel Wired LAN Driver Updates 2022-06-21
This series contains updates to ice driver only.
Marcin fixes GTP filters by allowing ignoring of the inner ethertype field.
Wojciech adds VSI handle tracking in order to properly distinguish similar
filters for removal.
Anatolii removes ability to set 1000baseT and 1000baseX fields
concurrently which caused link issues. He also disallows setting
channels to less than the number of Traffic Classes which would cause
NULL pointer dereference.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
ice: ethtool: Prohibit improper channel config for DCB
ice: ethtool: advertise 1000M speeds properly
ice: Fix switchdev rules book keeping
ice: ignore protocol field in GTP offload
