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.
