Subject: rsockets: Define options specific to rsockets
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=7c8fbc95903cf8f61422d7f2c58f83ba4f0b8ac4;p=~shefty%2Flibrdmacm.git

rsockets: Define options specific to rsockets

Allow a user to control some of the RDMA related attributes
of an rsocket through setsockopt/getsockopt.  A user specifies
that the rsocket should be modified through SOL_RDMA level.

This patch provides the initial framework.  Subsequent patches
will add the configurable parameters.
