RDMA/cxgb3: Streaming -> RDMA mode transition fixes
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.
