Hi,
it occurs to me that there is a potential infinite loop in
most if not all ethernet drivers. Basically, on a
receive interrupt, such drivers loop around the status word
until the receive queue is drained.
If the body of the loop takes approx the same as
the packet interarrival time, you might end up stuck in
the loop forever (and typically holding locks or with most
interrupts masked off).
I would suggest that we slightly redesign such loops so that
we limit the amt of time spent in them. This probably
affects only 100M/1G interfaces these days, but still...
cheers
