Subject: [PATCH v2 16/22] xprtrdma: Client-side support for rpcrdma_connect_private
Date: Tue, 23 Aug 2016 13:54:14 -0400	[thread overview]
Message-ID: <20160823175414.13038.69365.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20160823174402.13038.84561.stgit-FYjufvaPoItvLzlybtyyYzGyq/o6K9yX@public.gmane.org>

Send an RDMA-CM private message on connect, and look for one during
a connection-established event.

Both sides can communicate their various implementation limits.
Implementations that don't support this sideband protocol ignore it.

Once the client knows the server's inline threshold maxima, it can
adjust the use of Reply chunks, and eliminate most use of Position
Zero Read chunks. Moderately-sized I/O can be done using a pure
inline RDMA Send instead of RDMA operations that require memory
registration.
