I suppose, You've heard not about Cisco, but about Juniper. They ported FreeBSD to MIPS and then donated MIPS code back to FreeBSD: http://www.freebsd.org/news/newsflash.html 25 December: Juniper Networks, Inc.

This code will be used as one reference for creating an official project-supported FreeBSD/MIPS offering _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
