Subject: [PATCH 14/26] rdma/cm: add support for AF_IB to cma_get_service_id
Date: Thu, 1 Apr 2010 10:08:41 -0700 [thread overview]
Message-ID: <FDC38F513FED4F699910E7FC6D5BDAEB@amr.corp.intel.com> (raw)
In-Reply-To:
cma_get_service_id forms the service ID based on the port space
and port number of the rdma_cm_id. Extend the call to support
AF_IB, which contains the service ID directly. This will
be needed to support any arbitrary SID.
