Probably just me misremembering the error message...here the actual
message is:

[0,1,1][btl_openib_endpoint.c:945:mca_btl_openib_endpoint_create_qp]
ibv_create_qp: returned 0 byte(s) for max inline data
[0,1,1][btl_openib_endpoint.c:945:mca_btl_openib_endpoint_create_qp]
ibv_create_qp: returned 0 byte(s) for max inline data

It depends.  If there's lots of individual changes, it might be easier
to push the OFED 1.1 change.  But, that depends on when the final OFED
1.1 comes out and how much it varies from the existing RPMs.
