I don't believe that anyone has done an extensive analysis of the
performance of different network cards with regards to LVS. In terms of
100Mb/s it would make sense to me that you are going to want a reasonable
quality card. Intel eepro, DEC tulip based and 3Com cards fall into this
category for better or for worse. I've done all my work with eepro crads
because that's what I can get my hands on.

In terms of 1000Mb/s I've been having good success with Netgear acenic
cards of late, but again thats because I can get my hands on them.

To be honest, I think that the bigest problem you are going to come up
against is bus speed. Some performace testing I've been privy to lately
indicates a big advantage in using PCI 64bit/66MHz over  32bit/33MHz,
though this only really comes into play with gigabit.

No, but there is a HOWTO and a mailing list archive.
