In general it is needed as a fix because of the way learning with locked 
port is handled in the driver,
so as with MAB and also locked port in the future needing a non-zero 
Port Association Vector (PAV)
for refresh etc to work, inheritance of the locked port flag is a bad 
idea (say bug) and shouldn't have
been in the first place.
