My system designed with BF607 receives packet stream via ethernet.

I am using ethernet driver provided by ADI. Sometimes ADI ethernet driver does not work due to error occurrence while adi_ether_read() receives packets.

When ethernet error happens 0x00680000 is read from EMAC_DMA_STAT.

It corresponds to #4 in Rx Process State below. I would like to knwo what the conditions where Rx descriptor is unavailabe are.
