Hi Tim,
I fully understand the reason for the check.
However,
I think the bug has nothing to do with the rotting packet issue.
The bug is actually:
- eth_schedule_poll() gets called as it's detected that the ring is full
after IRQ_enable. (cown flag is set in the previous slot of the ring)

Hi All,
There seems to be a bug in the function eth_poll() in this driver
When the RX ring gets full once, the re-schedule is called forever, even
when the ring is empty afterwards.
if (!received) {
napi_complete(napi);
enable_irq(sw->rx_irq);
budget = 0;
