Otherwise,\nravb_tx_timeout_work() is possible to use the freed priv after\nravb_remove() was called like below:\n\nCPU0\t\t\tCPU1\n\t\t\travb_tx_timeout()\nravb_remove()\nunregister_netdev()\nfree_netdev(ndev)\n// free priv\n\t\t\travb_tx_timeout_work()\n\t\t\t// use priv\n\nunregister_netdev() will call .ndo_stop() so that ravb_stop() is\ncalled. And, after phy_stop() is called, netif_carrier_off()\nis also called. So that .ndo_tx_timeout() will not be called\nafter phy_stop()."
