[PATCH net-next 2/4] net: bridge: dsa: Add support for offloading of locked port flag

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Various switchcores support setting ports in locked mode, so that
clients behind locked ports cannot send traffic through the port
unless a fdb entry is added with the clients MAC address.

Among the switchcores that support this feature is the Marvell
mv88e6xxx family.
