(I'm assuming that you do not plan to merge this to releng/11.0.)

It looks like the changes to iflib.h will break any external NIC driver
written/compiled against the iflib.h in 11.0.  Is iflib considered part
of the KPI/KBI in FreeBSD 11 or is it for in-tree use only with no
interface guarantees?  If it's the latter then why do we even have iflib
in 11.0 given that no in-tree driver in 11.0 uses it?
