      RDMA/core: Add XRC domain support · 59991f94
      Sean Hefty authored
      XRC ("eXtended reliable connected") is an IB transport that provides
      better scalability by allowing senders to specify which shared receive
      queue (SRQ) should be used to receive a message, which essentially
      allows one transport context (QP connection) to serve multiple
      destinations (as long as they share an adapter, of course).
      
      A few new concepts are introduced to support this.  This patch adds:
      
       - A new device capability flag, IB_DEVICE_XRC, which low-level
         drivers set to indicate that a device supports XRC.
       - A new object type, XRC domains (struct ib_xrcd), and new verbs
         ib_alloc_xrcd()/ib_dealloc_xrcd().  XRCDs are used to limit which
         XRC SRQs an incoming message can target.
      
      This patch is derived from work by Jack Morgenstein <jackm@dev.mellanox.co.il>.
