Eric Dumazet bb6d5e76fb net/hyperv: fix erroneous NETDEV_TX_BUSY use ... A driver start_xmit() method cannot free skb and return NETDEV_TX_BUSY, since caller is going to reuse freed skb. This is mostly a revert of commit bf769375c (staging: hv: fix the return status of netvsc_start_xmit()) In fact netif_tx_stop_queue() / netif_stop_queue() is needed before returning NETDEV_TX_BUSY or you can trigger a ksoftirqd fatal loop. In case of memory allocation error, only safe way is to drop the packet and return NETDEV_TX_OK Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: "K. Y.
