Could you use the existing ofpbuf_at() instead of a new
ofpbuf_forward_ref()?  If there's no appropriate 'size' in a given
call then you can use 0.

It shouldn't be necessary to cast the return value of
ofpbuf_forward_ref() or ofpbuf_at(), generally, because they return
void *.

It isn't necessary to parenthesize the arguments to ALIGNED_CAST,
since the macro properly parenthesizes them internally.

Thanks,

Ben.
