Ah, sorry, thought I must have already complained to you about this
in the past - netlink aligns everything to 4B. So u8 or u16 or u32
it's all the same size at the message level. For the <u32 types some
bytes are just treated as padding instead of being useful.

But if you explicitly need only 0/1 then it doesn't matter.
