+Severity   : major
+Bugzilla   : 14634
+Description: socklnd prtocol version 3
+Details    : With current protocol V2, connections on router can be
+             blocked and can't receive any incoming messages when there is no
+             more router buffer, so ZC-ACK can't be handled (LNet message
+             can't be finalized) and will cause deadlock on router.
+             Protocol V3 has a dedicated connection for emergency messages
+             like ZC-ACK to router, messages on this dedicated connection
+             don't need any credit so will never be blocked. Also, V3 can send
+             keepalive ping in specified period for router healthy checking.

+Description: workaround for OOM from o2iblnd
+Details    : OFED needs allocate big chunk of memory for QP while creating
+             connection for o2iblnd, OOM can happen if no such a contiguous
+             memory chunk.
+             QP size is decided by concurrent_sends and max_fragments of
+             o2iblnd, now we permit user to specify smaller value for
+             concurrent_sends of o2iblnd(i.e: concurrent_sends=7), which
+             will decrease memory block size required by creating QP.

+Description: Support Zerocopy receive of Chelsio device
+Details    : Chelsio driver can support zerocopy for iov[1] if it's
+             contiguous and large enough.
