[Cialug] best supported/performing Ethernet adapter?

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
