Subject: RDMA/core: Assign device ifindex before publishing the device
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=273993509f05623934dda14a56237738149b2906;p=openwrt%2Fstaging%2Fblogic.git

RDMA/core: Assign device ifindex before publishing the device

Even though device->ifindex is assigned before adding the device in the
list which is read by netlink flow, it is better to assign rdma device
index before publishing the device in the system to users and clients.
