The NAPI instances get\ndisabled only once the last port goes down.\n\nThis causes an issue on the .remove() path where each port is\nunregistered and freed one at a time, causing the NAPI instances to be\ndeleted even though they are not disabled.\n\nIn order to avoid this, split up the unregister_netdev() calls from the\nfree_netdev() so that we make sure all ports go down before we attempt\na deletion of NAPI instances. Also, make the netif_napi_del() explicit\nas it is on the .probe() path."
