    tipc: change sk_buffer handling in tipc_link_xmit() · 22d85c79
    Jon Paul Maloy authored
    When the function tipc_link_xmit() is given a buffer list for
    transmission, it currently consumes the list both when transmission
    is successful and when it fails, except for the special case when
    it encounters link congestion.
    
    This behavior is inconsistent, and needs to be corrected if we want
    to avoid problems in later commits in this series.
    
    In this commit, we change this to let the function consume the list
    only when transmission is successful, and leave the list with the
    sender in all other cases. We also modifiy the socket code so that
    it adapts to this change, i.e., purges the list when a non-congestion
    error code is returned.
