+Description: Fixing deadlock in usocklnd
+Details    : A deadlock was possible in usocklnd due to race condition while
+             tearing connection down. The problem resulted from erroneous
+             assumption that lnet_finalize() could have been called holding
+             some lnd-level locks.

+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

+Bugzilla   : 18414
+Description: Fixing 'running out of ports' issue
+Details    : Add a delay before next reconnect attempt in ksocklnd in
+             the case of lost race. Limit the frequency of query-requests
+             in lnet. Improved handling of 'dead peer' notifications in
+             lnet.
