From: Moni Shoua <monis@xxxxxxxxxxxx>
Support in ODP with SRQ is considered as a per-transport capability.
Applications need to check that SRQ with ODP is supported if access to
an ODP MR happens with a QP that has a shared receive queue.
In addition, ibv_devinfo was updated to report this capability.
