could you please tell me if you're using tx interrupt or not?
if yes, why do you need to have a watchdog code implement
a txeof path and not the actual reset?
In normal operation, tx interrupts are not used and the sent
descriptors are cleaned up either by rx interrupts or by the watchdog.
The sole exception is when the tx queue is full.
exactly, so please don't do it. use a tx interrupt for txeof and use a
watchdog to reset a "controller".
Always using the tx interrupt decreases performance significantly. On my
test system (in MBytes/s):
Sending UDP from 75 to 55
Sending TCP from 34 to 25
I dont' think we want to do this.
