Following are some common parameters that can be changed:

rx-usecs and rx-frames control the RX interrupt rate per RX DMA channel. RX
interrupt will be generated after rx-frames have been received or after rx-usecs
time interval if fewer than rx-frames have been received within the interval. For
low latency applications, it is recommended to set rx-usecs to smaller value. For
bulk traffic, it is recommended to use larger values of rx-usecs and control the
rate with rx-frames.

rx-frames-irq controls the maximum number of rx packets processed with a single
RX interrupt.
