[Cialug] best supported/performing Ethernet adapter?

I asked based on the rumors about the quality of their compiler -  I won't
be afraid of their drivers.
I have a mini-itx machine at home (RHINE Ethernet Chip) with a lot of disk
space on it.  I was copying video to it at the same time I was playing video
from it and it started to balk after a couple hours.  It does fine most of
the time, but apparently sometimes, I ask too much of it.

I wouldn't put Realtek in a server, but for a home machine, it is just fine
and very cheap. 

Yes Intel writes their own driver.  You can get the source code from their
website.  I was talking with one of our engineers and he is very impressed
with the Intel driver.  The common code is clearly separated from the OS
specific code so porting the driver to new OSs is very easy.

Realtek does OK until you pound on it with something like video+file
Does Intel write/contribute their own Linux driver?

Intel seems to be the best for: 

- performance 
- multiple OS support 
- leading edge features like jumbo packet, VLAN, QOS 

We use a lot of their 1000G dual fiber and dual copper server cards with
Linux.  They also seem to regularly update their driver several times per
year for bug fixes and improvements. 

You get what you pay for...all will pass ethernet packets around, but you
pay more money to get higher performance, better drivers, leading edge
features.  I use Realteks at home since I need some to just pass
