[rds-devel] Has anyone tried running RDS over 10GE / IWARP NICs ?

Steve, we would like to get RDS running over the Chelsio 10GE NICs .

It looks like there is some sort of a problem - we are assuming it is 
something simple - as RDS does not do much more than connect over an RC 
and do send / recvs.

Can you help us move this forward - either by looking at this yourself 
and or putting in contact with folks that can ?
