I can't see why; if_flags doesn't appear anywhere where endianness is
relevant as far as I know (no wire protocols, for example).  I didn't
have any endianness issues when just growing the field on 1.4T, and I
use hardware of each endianness regularly.  And if endianness mattered,
wouldn't we have such issues today with the existing field, since it's
already more than one byte?
