Due to a HW issue, our current scheme to transition the connection from
streaming to rdma mode is broken on the passive side. The firmware
and driver now support a new transition scheme for the passive side:
- driver posts rdma_init_wr (now including the initial receive seqno)
- driver posts last streaming message via TX_DATA message (MPA start
response)
- uP atomically sends the last streaming message and transitions the
tcb to rdma mode.
- driver waits for wr_ack indicating the last streaming message was ACKed.
NOTE: This change also bumps the required firmware version to 4.3.

Update FW to 4.1.
Proceed to subsequent HW tuning to improve RDMA perfs..

The HW now posts 2 ABORT_RPL and/or PEER_ABORT_REQ messages. We need
to handle them by silenty dropping the 1st but mark that we're ready
for the final message. This plugs some close races between the uP and
HW. Also update the minimum required firmware version.
