    ramips/mediatek: import a patch fixing bug in flow-offloading
    
    From Frank Wunderlich <frank-w at public-files.de>:
    Issue were traffic problems after a while with increased ping times if
    flow offload is active.
    
    It turns out that key_offset with cookie is needed in rhashtable_params
    and head_offset was defined twice.
