====================
Intel Wired LAN Driver Updates 2021-12-15

This series contains updates to igb, igbvf, igc and ixgbe drivers.

Karen moves checks for invalid VF MAC filters to occur earlier for
igb.

Letu Ren fixes a double free issue in igbvf probe.

Sasha fixes incorrect min value being used when calculating for max for
igc.

Robert Schlabbach adds documentation on enabling NBASE-T support for
ixgbe.

Cyril Novikov adds missing initialization of MDIO bus speed for ixgbe.

a virtual function (VF), jumbo frames must first be enabled in the physical
function (PF). The VF MTU setting cannot be larger than the PF MTU.
NBASE-T Support
---------------
The ixgbe driver supports NBASE-T on some devices. However, the advertisement
of NBASE-T speeds is suppressed by default, to accommodate broken network
switches which cannot cope with advertised NBASE-T speeds. Use the ethtool
command to enable advertising NBASE-T speeds on devices which support it::
ethtool -s eth? advertise 0x1800000001028
On Linux systems with INTERFACES(5), this can be specified as a pre-up command
in /etc/network/interfaces so that the interface is always brought up with
NBASE-T support, e.g.::
iface eth? inet dhcp
pre-up ethtool -s eth? advertise 0x1800000001028 || true
Generic Receive Offload, aka GRO
--------------------------------
The driver supports the in-kernel software implementation of GRO. GRO has
