Attempt to support NetBSD
...
This code actually consolidates a lot of the BSD code together, and even setting the interface MTU with SIOCSIFMTU seems to work fine.
What doesn't work though is setting the interface address using SIOCSIFADDR_IN6, which I attempted to plagiarise from the Darwin code.
As a fallback, ifconfig is used, which solves the problem enough to get it working.
