Just patched the stuff u gave me the other day, it works!  At least 
it got improved...

I installed the patch, recompiled my kernel, and now I'm able to send out 
big packets.  Tho it freezed when I telneted onto gold.tc.umn.edu and tried to
get a 16MB file from Ngbert.  Normal transfers r ok, like http and stuff.

I have to c if my network can keep running for tomorrow or something...
I had to reboot my machine six times today due to the former problem.

I hope I don't need to reboot it anymore tomorrow.  If it goes well, I will
write u a mail telling u how to patch the stuff.  or u could consult
the patch manpage.

thx!
