Nguyen, Anthony L says:

====================
Intel Wired LAN Driver Updates 2021-05-07

This series contains updates to i40e driver only.

Magnus fixes XDP by adding and correcting checks that were caused by a
previous commit which introduced a new variable but did not account for
it in all paths.

Yunjian Wang adds a return in an error path to prevent reading a freed
pointer.

Jaroslaw forces link reset when changing FEC so that changes take
affect.

Mateusz fixes PHY types for 2.5G and 5G as there is a differentiation on
PHY identifiers based on operation.

Arkadiusz removes filtering of LLDP frames for software DCB as this is
preventing them from being properly transmitted.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  i40e: Remove LLDP frame filters
  i40e: Fix PHY type identifiers for 2.5G and 5G adapters
  i40e: fix the restart auto-negotiation after FEC modified
  i40e: Fix use-after-free in i40e_client_subtask()
  i40e: fix broken XDP support
