Vivien Didelot says:

====================
net: dsa: mv88e6xxx: add PCL support

This small series implements the ethtool RXNFC operations in the
mv88e6xxx DSA driver to configure a port's Layer 2 Policy Control List
(PCL) supported by models such as 88E6352 and 88E6390 and equivalent.

This allows to configure a port to discard frames based on a configured
destination or source MAC address and an optional VLAN, with e.g.:

    # ethtool --config-nfc lan1 flow-type ether src 00:11:22:33:44:55 action -1
