Michael,
   Actually 'rcq' is being used for handling the 'start' and 'done' messages.
As for the lid, qpn, psn, rkey and vaddr, these gets exchanged as part of the 
rdma_listen/rdma_connect calls. See pp_server_connect and pp_client_connect.
OTH I tried testing rdma_bw on Ammasso iWARP without exchanging the 'start' and 
'done' messages and it worked. I am not sure if this is the right thing to do. 
Maybe Steve can throw more light on this.

Thanks,
Pradipta
