Should that be completely dropped, or is it still ok ? (I think
differenciating action based on hard_start_xmit status, that is, don't
goto repeat undefinitely when NETDEV_TX_BUSY, could be a good idea).
I mean, should I rework that patch, forget about it or leave it as-is?
Concerning the hang, I see that Andrew has put my first patch, the one
checking for netif_carrier_ok(), in his tree. Is it an OK solution from
your (net dev hackers) point of view?
Thanks,
