- * Example: suppose that 'sf->field' is originally the following 2-byte field
- * in 'rule':
- *
- * value == 0xe00a == 2#1110000000001010
- * mask == 0xfc3f == 2#1111110000111111

- * The call mf_set_subfield(sf, 0x55, 8, 7, rule), where sf->ofs == 8 and
- * sf->n_bits == 7 would have the following effect (note that 0x55 is
- * 2#1010101):

- * value == 0xd50a == 2#1101010100001010
- * mask == 0xff3f == 2#1111111100111111

- * that 'rule' meets 'sf->field''s prerequisites. */
