    realtek: eth: drop pick queue functions
    
    The operating system has enough features to control the transmit
    queues. There is no need to provide a hard coded distribution
    function. Especially differentiating between a round robin for
    RTL83xx and high/low priority for RTL93xx makes no sense. All
    devices have the same low/high priority queues.
    
    Simply present two "generic" queues to the kernel.
