OK, you got me worried - I did some testing with a net4511, and sure 
enough, I was able to kill it with a single TCP connection at maximum 
speed (which turned out to be about 16 Mbps) after only 25 seconds. It 
just reset, no kernel panic, no messages, no nothing. Scary! I tried 
with BIOS versions 1.15a and 1.22 - no difference (as expected).

I still do not believe that this is a m0n0wall problem (and hence needs 
to be fixed by me) at all, though. Here's why:

I did the very same experiment with a net4801 and a PC Engines WRAP 
board. I was unable to get them to reset even after 10 minutes. I also 
tried hitting them hard with a 90 Mbps UDP stream for five minutes 
each. No reset. The net4801 actually passed 57 Mbps, while the WRAP did 
about 66 Mbps. Funny because the WRAP board I have has a 233 MHz CPU 
while the net4801 has a 266 MHz one, but that's got nothing to do with 
this problem.

Now, using polling mode seems to circumvent this problem, so I quickly 
whipped together a net45xx image with a kernel that supports polling 
(with HZ=1000, and a call in rc.bootup to enable it):

Not sure if it helps those with wireless cards though (the wi driver 
doesn't support polling).
