    gianfar: Bundle Rx allocation, cleanup · 76f31e8b
    Claudiu Manoil authored
    Use a more common consumer/ producer index design to improve
    rx buffer allocation.  Instead of allocating a single new buffer
    (skb) on each iteration, bundle the allocation of several rx
    buffers at a time.  This also opens the path for further memory
    optimizations.
    
    Remove useless check of rxq->rfbptr, since this patch touches
    rx pause frame handling code as well.  rxq->rfbptr is always
    initialized as part of Rx BD ring init.
    Remove redundant (and misleading) 'amount_pull' parameter.
