Could you please verify? Nothing in the base system uses it. Initially,
ifr_prevflags was added with the following log message (rev.1.50):
Since ifru_flags is a short, we can fit in a copy of the flags
before they got changed. This can help eliminate much of the
gymnastics drivers do in their ioctl routines to figure this out.
but no drivers are using it so far.
Just in the case, attached is updated patch, which utilises ifr_prevflags
for extending ifr_flags.
