[openib-general] [PATCH][iWARP] Added provider CM verbs andquery provider methods

[Steve Wise]

There is mention in the chelsio TOE thread that one reason you want TOE 
nics is so that you can then do RDMAP on top of TCP on the adapter, and 
get direct placement and kernel bypass...

Yes. I guess it's not obvious that the topics are related. Since
our RDMA transport runs on top of TCP and since the RDMAC verbs
spec requires that we have an LLP Handle (socket), we are dependent on
the resolution of this issue.
