Hi everyone, Many thanks to everyone involved, either fixing ports, reviewing changes, or assisting with the API, struct ifnet is now hidden from drivers and userspace. This means drivers now use the IfAPI, currently largely consisting of just getters and setters in place of direct access, with tools/ifnet/convert_ifapi.sh being a good starting point for adapting drivers. In struct ifnet's place is if_t, an opaque pointer. "Blessed" parts of the kernel, effectively anything sys/net*, modulo sys/netlink, can directly access it, as those directories comprise the network stack, so need direct access, as they manage the interfaces. Manpage updates will be coming "soon", I'm hoping in the next few weeks, and will likely need lots of review and editing. Again, thanks for everyone's help. I hope the road forward with this is not too bumpy. - Justin
