In mf_mask_subfield_wc(), for MFF_IN_PORT and MFF_IN_PORT_OXM, I would
set the whole field unconditionally to all-1-bits. (We don't allow
bitwise matching on input ports and I hope we never do.) Same for
MFF_ETH_TYPE, although bitwise matching there is a little less crazy.
There's an extra space on this line:
bitwise_one (&value, field->n_bytes, sf->ofs, sf->n_bits);
