This is a method that is not supported by the iWARP transport. ENOSYS
indicates this. I _think_ this is SOP for the infinband subsystem.
Roland, I think at one time we were talking about changing the Core to
better handle this? Either with attributes/capabilities that the low
level driver can set, or by set these method ptrs to NULL and the core
should handle it in the wrapper function...
Steve.
