Oh this is a mistake the tests need to the use APIs to get this
information not muck about in sysfs.

Yes. netlink and the gid table reports the netdev for all rdma
devices, that is what the tests should be using.
Call ibv_query_gid_table(), put every ndev_ifindex in a set, then that
set is the list of every netdev index affiliated with the rdma device.
if_indextoname() will convert to a string name
