+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
