[ofa-general] [PATCH 1/4] rdma/addr: keep the netdevice name in struct rdma_dev_addr

Keep also the local (src) netdevice name in struct rdma_dev_addr. In a High-Availability
scheme this can be used by the rdma-cm to align RDMA sessions to use the same links as
the IP stack does under fail-over and route change cases.
