It's an array of enums, so can call it that way instead.

Just for reference, I tried
https://github.com/ideak/linux/commit/de8daa5362ce

but I didn't find it simple/generic/fast-to-compile enough.

There's also the planned
https://www.mail-archive.com/netdev@xxxxxxxxxxxxxxx/msg402394.html
and
https://www.mail-archive.com/netdev@xxxxxxxxxxxxxxx/msg402398.html

This one requires disabling some 'struct-field-reinited' warning, not
sure if it's getting merged or not.
