    net: txq_trans_update() helper · 08baf561
    Eric Dumazet authored
    We would like to get rid of netdev->trans_start = jiffies; that about all net
    drivers have to use in their start_xmit() function, and use txq->trans_start
    instead.
    
    This can be done generically in core network, as suggested by David.
    
    Some devices, (particularly loopback) dont need trans_start update, because
    they dont have transmit watchdog. We could add a new device flag, or rely
    on fact that txq->tran_start can be updated is txq->xmit_lock_owner is
    different than -1. Use a helper function to hide our choice.
