    net: Optimize hard_start_xmit() return checking · 9a1654ba
    Jarek Poplawski authored
    Recent changes in the TX error propagation require additional checking
    and masking of values returned from hard_start_xmit(), mainly to
    separate cases where skb was consumed. This aim can be simplified by
    changing the order of NETDEV_TX and NET_XMIT codes, because the latter
    are treated similarly to negative (ERRNO) values.
    After this change much simpler dev_xmit_complete() is also used in
    sch_direct_xmit(), so it is moved to netdevice.h.
    Additionally NET_RX definitions in netdevice.h are moved up from
    between TX codes to avoid confusion while reading the TX comment.
