From: Chuck Lever <chuck.lever@xxxxxxxxxx> A non-zero MAC address enables a network device to be assigned as the underlying device for a virtual RDMA device. Without a non- zero MAC address, cma_acquire_dev_by_src_ip() is unable to find the underlying egress device that corresponds to a source IP address, and rdma_resolve_address() fails.
