Right -- in fact, as I recall, Mogul's paper mentions that his
solution is very similar to the way many RTOSes operate.

One possible right way to deal with this is to get rid of the
two-level int
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 migh
