    net: dsa: Refactor transmit path to eliminate duplication · 4ed70ce9
    Florian Fainelli authored
    All tagging protocols do the same thing: increment device statistics,
    make room for the tag to be inserted, create the tag, invoke the parent
    network device transmit function.
    
    In order to prepare for adding netpoll support, which requires the tag
    creation, but not using the parent network device transmit function, do
    some little refactoring which eliminates duplication between the 4
    tagging protocols supported.
    
    We need to return a sk_buff pointer back to the caller because the tag
    specific transmit function may have to reallocate the original skb (e.g:
    tag_trailer.c) and this is the one we should be transmitting, not the
    original sk_buff we were passed.
