rpc - cleanup and changes related to rdma
- remove rpc_conn_state structure. - add a member to point struct rpc_req in rpc_transport_req structure. This is needed for rdma to store rdma specific per request data. Signed-off-by: Raghavendra G <raghavendra@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 875 (Implement a new protocol to provide proper backward/forward compatibility) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=875
