    bridge: Save frag_max_size between PRE_ROUTING and POST_ROUTING · 93fdd47e
    Herbert Xu authored
    As we may defragment the packet in IPv4 PRE_ROUTING and refragment
    it after POST_ROUTING we should save the value of frag_max_size.
    
    This is still very wrong as the bridge is supposed to leave the
    packets intact, meaning that the right thing to do is to use the
    original frag_list for fragmentation.
    
    Unfortunately we don't currently guarantee that the frag_list is
    left untouched throughout netfilter so until this changes this is
    the best we can do.
    
    There is also a spot in FORWARD where it appears that we can
    forward a packet without going through fragmentation, mark it
    so that we can fix it later.
