It seems to be targeted at FreeBSD 4.2, which is very old indeed. 2. No mention of it in GNATS or the mailing list that I can see or recall= =2E 3. I'd certainly never heard of it until now, and I've been keeping my=20 eyes peeled for these things. Also the work doesn't seem to be complete: I'm really not sure that the=20 ability to open an MPLS socket is useful in anything other than an=20 experimental context. MPLS is not a protocol which is designed with end-stations in mind --=20 it's for routers -- and like any form of traffic engineering, it depends = on a packet filtering engine at the ingress point. pf could offer such a = filtering engine. Whilst it's very cool that someone appeared to have done some of the=20 work... Matthew Luckie came forward a few months back and volunteered=20 to work on porting Ayame to modern FreeBSDs. It is more likely a better fit for FreeBSD and other projects which can=20 build on it, so I think it is best we hold off for now. regards, BMS
