* Mr. Arai said PLANET FNW-3600-T is the OEM of LINKSYS EtherFast * 10/100 and it is woking under ed driver with a patch. Thanks! I got it to work with PAO-980430 (2.2.6R). Boy this thing is slow (something like 1.2MB/s over a 100Mbps link) but it's good enough for my purpose (connect the laptop to a stupid 100Mbps hub). :) * http://www.jp.FreeBSD.ORG/~yuki/FreeBSD/readmail.cgi?source=nomads&docnum=7152 * (sorry in Japanese :-) I can read that, no problem. :) Anyway, here's the patch for anyone who might be wondering. It's almost the same as the patch in the above-mentioned article (only one hunk fails due to NCRD -> NCARD change).
