CONFIG_NET CONFIG_NETDEVICES CONFIG_NET_ETHERNET CONFIG_NET_PCI CONFIG_EEPRO100
The networkcard is a standard EtherExpress Pro 100, which is pretty popular these days. Therefore, the support is quite good.
I think Linus has one too, BTW: if you don't modify anything about your kernel configuration when building from source, the EtherExpress Pro will be the only NIC supported by your kernel...
No real problems here.
I received a mail from Jeff Chua mailto:jchua@fedex.com who told me that he experienced slowdowns on network traffic with the eepro100 driver, something he didn't notice using the ``e100'' one. Maybe I'm lucky, maybe I don't use my network as much as he does, maybe I'm just not used to 100MBit, but I don't have that problem; if you do, you might want to try this suggestion.
If you're compiling your own kernel, you'll want to compile this as a module, so that you can unload the module when you're not using your network card. Your battery will like that, and live a bit longer in return ;-)
