This requires a full checkout of the FreeBSD 8.2 source code. The checkout we have been using is missing at least the libc, include, and sys directories. The script to copy files in is crude. This eventually needs to separate the manually written .h files out and add the RTEMS specific network initialization support with functionality to program the IP addresses and gateways as the old stack did.
