Why FreeBSD-specific?

Perhaps we should refactor this into a muge_set_mac_addr or such first? Or I'm happy to do it afterwards.

Some suggestions but overall I think this is fine. I can futz with it after commit otherwise.

extra 'r' in store

matching

This comment is probably not correct (at least, not correct at this location) now.

1569–1570 ↗(On Diff #44828)

Given this is moved out into a function we could use early-return instead
