net: net: add a core netdev->tx_dropped counter
Dropping packets in __dev_queue_xmit() when transmit queue is stopped (NIC TX ring buffer full or BQL limit reached) currently outputs a syslog message. It would be better to get a precise count of such events available in netdevice stats so that monitoring tools can have a clue. This extends the work done in caf586e5f23ce ("net: add a core netdev->rx_dropped counter") Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
