From: Erez Shitrit <ere...@nvidia.com>
Till now the FDB processing domain is split into two mutually
exclusive sub domains FDB_RX and FDB_TX.
Packets originating from the Uplink(s) are processed in the FDB_RX
sub domain, while packets originating from all other Vports are
processed in the FDB_TX sub domain.
Now adding new sub domain: FDB_UNIFIED which can process packets
originated by any VPORT / WIRE.
This new domain will process actions only that allowed on both RX
and TX domains.
That way the user can define specifically the domain he wants the
packet to be processed, whenever it is RX/TX only he will use
FDB_RX/TX, or whenever it can by FDB_UNIFIED.
