    net: mscc: ocelot: use common tag parsing code with DSA · 40d3f295
    Vladimir Oltean authored
    The Injection Frame Header and Extraction Frame Header that the switch
    prepends to frames over the NPI port is also prepended to frames
    delivered over the CPU port module's queues.
    
    Let's unify the handling of the frame headers by making the ocelot
    driver call some helpers exported by the DSA tagger. Among other things,
    this allows us to get rid of the strange cpu_to_be32 when transmitting
    the Injection Frame Header on ocelot, since the packing API uses
    network byte order natively (when "quirks" is 0).
    
    The comments above ocelot_gen_ifh talk about setting pop_cnt to 3, and
    the cpu extraction queue mask to something, but the code doesn't do it,
    so we don't do it either.
