While being marked deprecated, it allows a lockless tx path : The device transmit handler can then perform custom actions, including its own locking if needed. If the user wants a specific Qdisc setup (instead of a no qdisc one), it still can. veth, loopback, dummy, macvlan & bond devices use NETIF_F_LLTX for example. But ndo_start_xmit() must always be called with BH disabled. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
