tun: return NET_XMIT_DROP for dropped packets
After commit 5d097109 ("tun: only queue packets on device"), NETDEV_TX_OK was returned for dropped packets. This will confuse pktgen since dropped packets were counted as sent ones. Fixing this by returning NET_XMIT_DROP to let pktgen count it as error packet. Cc: Michael S. Tsirkin <mst@redhat.com> Signed-off-by:Jason Wang <jasowang@redhat.com> Signed-off-by:
