Under "heavy" RX load, the driver cannot handle the descriptors fast enough. In detail, when a descriptor is consumed, its used flag is cleared and once the RX budget is consumed all descriptors with a cleared used flag are prepared to receive more data. Under load though, the HW may constantly receive more data and use those descriptors with a cleared used flag before they are actually prepared for next usage. The head and tail pointers into the RX-ring should always be valid and we can omit clearing and checking of the used flag.
