    net: enetc: increase RX ring default size · d6a2829e

    As explained in the XDP_TX patch, when receiving a burst of frames with
    the XDP_TX verdict, there is a momentary dip in the number of available
    RX buffers. The system will eventually recover as TX completions will
    start kicking in and refilling our RX BD ring again. But until that
    happens, we need to survive with as few out-of-buffer discards as
    possible.
    
    This increases the memory footprint of the driver in order to avoid
    discards at 2.5Gbps line rate 64B packet sizes, the maximum speed
    available for testing on 1 port on NXP LS1028A.
