Odd HAPPY MEAL behaviour (sunhme.c).
Hi,
Have previously installed Linux (2.2.13) on a SUN Ultra 5 333Mhz
with two Quad NICs. I have a problem with network delays, even with
crossover cables. A simple ping from another host looks like this,

[helios]$ ping -s bussola

It's the same pattern from every host I try from and the peek is almost
always at 1001.1 ms or 1001.2 ms, but not when I ping simultaneously from
another host.

Note the difference in response when pinging from two hosts
simultaneously.
Anyone have any ideas?
