>Description:
I think this is related to kern/29794 and kern/29742.

I cvsup'd to -stable around 10:00am Wed August 15, 2001 EDT, but didn't
start excercising it until the next day, when I discovered that 
TCP/IP connectivity was abysmal.

I first noticed the abysmal connectevity when I tried to start `arla'
(`ports/net/arla', and discovered that my ethernet connection at work
was even worse than my piddly dialip connection at home.

After some poking around, I discovered a most unusual fact:
If I ran 'ping -c 1000 -i 10 -s 1200 <a-host-on-the-same-subnet/LAN>'
I got delays of 2 seconds. Even more unusual was the delay would
drop by 10 ms every 'ping' packet, until the delay reached 1.1 seconds,
when the delay would reset to 2 seconds.

This is very frustrating, as I don't have a way to easily connect to
a network right now. (I suppose I'll have to use an external modem.)

B.T.W.: Another box I have (an ancient Gateway 2000 P5-120) is still
working, but it just isn't portable. It was upgraded later that
day, and again after I ran into troubles with the laptop. I'm trying
to keep a full CVS archive of 'src-all' on this machine.
