number of retry to be performed whenever controller found RX descriptor was empty. RX empty interrupt is generated only when the retry counter is over. Experimentation shows retrying RX descriptor loading increased number of dropped frames under flow-control enabled environments so disable it and have controller generate RX empty interrupt as fast as it can. While I'm here fix RXCSR_DESC_RT_CNT macro. |
