When a packet is sent back to iWARP FW via the tx ll2 connection
the FW needs to know the source of the packet. Whether it is
OOO or unaligned MPA related. Since OOO is implemented entirely
inside the ll2 code (and shared with iSCSI), packets are marked
as IN_ORDER inside the ll2 code. For unaligned mpa the value
will be determined in the iWARP code and sent on the pkt->vlan
field.
