Tony Nguyen says:

====================
40GbE Intel Wired LAN Driver Updates 2021-02-10

This series contains updates to i40e driver only.

Arkadiusz adds support for software controlled DCB. Upon disabling of the
firmware LLDP agent, the driver configures DCB with default values
(only one Traffic Class). At the same time, it allows a software based
LLDP agent - userspace application i.e. lldpad) to receive DCB TLVs
and set desired DCB configuration through DCB related netlink callbacks.

Aleksandr implements get and set ethtool ops for Energy Efficient
Ethernet.

Przemyslaw extends support for ntuple filters allowing for Flow Director
IPv6 and VLAN filters.

Kaixu Xia removes an unneeded assignment.
