RDMA/netdev: Fix netlink support in IPoIB
IPoIB netlink support was broken by the below commit since integrating
the rdma_netdev support relies on an allocation flow for netdevs that
was controlled by the ipoib driver while netdev's rtnl_newlink
implementation assumes that the netdev will be allocated by netlink.
Such situation leads to crash in __ipoib_device_add, once trying to
reuse netlink device.
This patch fixes the kernel oops for both mlx4 and mlx5
devices triggered by the following command:
