    netfilter: Pass net into okfn · 0c4b51f0
    Eric W. Biederman authored
    This is immediately motivated by the bridge code that chains functions that
    call into netfilter.  Without passing net into the okfns the bridge code would
    need to guess about the best expression for the network namespace to process
    packets in.
    
    As net is frequently one of the first things computed in continuation functions
    after netfilter has done it's job passing in the desired network namespace is in
    many cases a code simplification.
    
    To support this change the function dst_output_okfn is introduced to
    simplify passing dst_output as an okfn.  For the moment dst_output_okfn
    just silently drops the struct net.
