Hmm... Is this issue (ICMP packets being dropped due to lazy locking)
supposed to be fixed in current 2.4 (2.4.22pre4, for example)?  I seem
to still be seeing ICMP packet loss with duplextest which disappears
if I bind the NIC interrupt to one of the two CPUs (e100 driver).

I checked the code and the patch appears to be in there.  I wonder what
is causing the loss now... tcpdump on the machine being pinged shows
it not responding to all of the ICMP it receives, as was happening
before.
