    bce: Disable RX max BDs based interrupt moderation
    
    The RX max coalesce BDs is limited to 255, which means that the chip will
    generate ~5800 interrupts/s when it sinks 1.48Mpps tiny packets.  However,
    interrupt rate at 4500Hz is already enough for the chip to sink 1.48Mpps
    tiny packets, so ticks based RX interrupt moderation should be prefered.
