Why lagg(4) wants ~IFF_DRV_OACTIVE?

Hi,

Maybe this is a stupid question but I really don't understand why a
interface with IFF_DRV_OACTIVE can't be added to a lagg(4) interface.
Looking at OpenBSD code, they do this since the day 0.

Could anyone shed some light, why we need to enforce this check? :)

Cheers,
