I have a new UPS for my router that uses the NUT 'netxml' driver. This is typically available in the linux package "nut-drivers-net" however this has not been packaged for OpenWRT as far as I can tell (unless it's been significantly renamed).
As it's a standalone driver binary, is it possible to just pull it off another x86_64 system and drop it in the /lib/nut directory with the other drivers?
