RDMA/cxgb3: Adjust ORD/IRD (if needed) for peer2peer connections
NFS/RDMA currently fails to set up connections if peer2peer is on. This is due to the fact that the NFS/RDMA client sets its ORD to 0. If peer2peer is set, make sure the active side ORD is >= 1 and the passive side IRD is >=1. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
