A driver start_xmit() method cannot free skb and return NETDEV_TX_BUSY, since caller is going to reuse freed skb. 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 Also increments tx_dropped counter Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com> Signed-off-by: David S.
