I was wondering if it is possible to assign a vlan bitmap for the FDB
entry, instead of replicating the entry for each vlan. ( I believe
Roopa has done something similar, but not so sure). This means that
the number of FDB entries remain static for any number of vlans.

I guess its more complicated than it sounds, but just wanted to know
if its feasible at all.
