What I found works is freebsd 4.x, and a Pentium 2 350-400Mhz this was using risecom n/2 cards. FreeBSD 6.1 doesen't work at any speed in this combo, it loses packets. It's a driver bug, the sr driver needs a rethink of it's buffer structures. also, there's a bug with the wanic 2 port cards that isn't present in the risecom/n2 2 port cards, they drop characters when both ports are active. With Cisco 1601's selling on the used market for $25 or so, there's little interest among the developers in fixing this. Also the wanic 4xx is no longer in production, another disincentive. It would be interesting benchmarking this with Imagestream's Linux-only drivers.
