Also, there is an issue with ifconfig and TR. During the 2.3 dev kernels we changed the IEEE type of TR from 6 to a value in the 800 range. This was done when multicast support was added as we needed to split out TR from the other 802 protocols. ifconfig and friends didn't realize this and barf because the return type is wrong. I've tried submitting patches to net-tools for this several times, but it wasn't fixed. It may be by now, but don't quote me on it. Mike Phillips Linux Token Ring Project http://www.linuxtr.net
