vss1980,
The 3Com 3C509 will be supported under Klinux, as there are a lot of them floating around.
All the 3Com cards will be supported in the Klinux-v.3B version.
I did the poll, basicly to give me an idea what nics people are running.
I might drop a few of the less known or used nics off the list.
As far as the Realtek nics, they will also be supported, as there's a wide variety of vendors using their chips.
The Realtek 8019 however, is the one that dosn't have any Linux support at all.
Any nic that runs a generic driver, like the Netgear and Linksys LNTX100's, any MX (Micronics) based, will run the "DECchips Tulip" drivers, will be supported.
<Edit- RC, I believe you.
