+Severity : major
+Bugzilla : 13621, 15983
+Description: Protocol V2 of o2iblnd
+Details : o2iblnd V2 has several new features:
+ . map-on-demand: map-on-demand is disabled by default, it can
+ be enabled by using modparam "map_on_demand=@value@", @value@
+ should >= 0 and < 256, 0 will disable map-on-demand, any other
+ valid value will enable map-on-demand.
+ Oi2blnd will create FMR or physical MR for RDMA if fragments of
+ RD > @value@.
+ Enable map-on-demand will take less memory for new connection,
+ but a little more CPU for RDMA.
+ . iWARP : to support iWARP, please enable map-on-demand, 32 and 64
+ are recommanded value. iWARP will probably fail for value >=128.
+ . OOB NOOP message: to resolve deadlock on router.
+ . tunable peer_credits_hiw: (high water to return credits),
+ default value of peer_credits_hiw equals to (peer_credits -1),
+ user can change it between peer_credits/2 and (peer_credits - 1).
+ Lower value is recommended for high latency network.
+ . tunable message queue size: it always equals to peer_credits,
+ higher value is recommended for high latency network.
+ . It's compatible with earlier version of o2iblnd

+Severity : major
+Bugzilla : 14634
+Description: socklnd protocol 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.
