For the record, the existing linux RNICS don't exactly work this way:
Ammasso handles all TCP connection setup and MPA negotiation in HW/FW.
The connection setup interface between the RNIC and host driver are
strictly for RDMA connections.
Chelsio has a message based interface to the HW/FW for establishing
TCP connections and exchanging data in streaming mode. No TCP
processing is done in the driver.
