When it (Linux network) works fine, it works fine.
But it ofen gives me the packet loss erros.  It is mostly fine as your
stats show.  The packet loss is not really bothering.  However, the following 
problem makes Linux box almost unusable on network.

Our network consists of machines with DEC/Ultrix, NeXT, and SUN-OS.
All work fine together. They are clients/servers each other.  Only Linux
causes the above problem.  
Don't ask me about patience. For a long time, I have been patiently 
waiting for the patch which would resolve the problem.  Whenever the
new patch is available, I immediately patched it and recompiled, hoping
that the problem be solved.  I had been doing this since 0.99.x until 1.1.xx.
Oh, no more. 
I tested NetBSD and FreeBSD,  - NO PROBLEM AT ALL.
Before I started FreeBSD, I never thought that FreeBSD is this good.

Since FreeBSD is becoming more and more user-friendly (I mean, installation
procedure - even though it still needs more jobs to attract *average/novice* 
unix users) it *might* be the choice of Free Unix system for the future.

As I said, I am not the only one who has the above problem.  I have seen
(at least three) postings on linux news group which reported the above
problem.  And they all had different network cards (better than NE2000).
In fact, one guy reported that he tried several kinds of network cards,
since he suspected them, but the problem was there with all the cards that
he tried.  Also, if it was the NE2000's problem, why does it work with *BSD 
without any problem ?
