    net: mscc: ocelot: simplify tc-flower offload structures · a56d7a34
    Vladimir Oltean authored
    The ocelot tc-flower offload binds a second flow block callback (apart
    from the one for matchall) just because it uses a different block
    private structure (ocelot_port_private for matchall, ocelot_port_block
    for flower).
    
    But ocelot_port_block just appears to be boilerplate, and doesn't help
    with anything in particular at all, it's just useless glue between the
    (global!) struct ocelot_acl_block *block pointer, and a per-netdevice
    struct ocelot_port_private *priv.
    
    So let's just simplify that, and make struct ocelot_port_private be the
    private structure for the block offload. This makes us able to use the
    same flow callback as in the case of matchall.
    
    This also reveals that the struct ocelot_acl_block *block is used rather
    strangely, as mentioned above: it is defined globally, allocated at
    probe time, and freed at unbind time. So just move the structure to the
    main ocelot structure, which gives further opportunity for
    simplification.
    
    Also get rid of backpointers from struct ocelot_acl_block and struct
    ocelot_ace_rule back to struct ocelot, by reworking the function
    prototypes, where necessary, to use a more DSA-friendly "struct ocelot
    *ocelot, int port" format.
    
    And finally, remove the debugging prints that were added during
    development, since they provide no useful information at this point.
