49 *
50 * TS 48.016 V9.0.0 (2010-02), in that section, says, of information elements:
51 *
52 * When a field extends over more than one octet, the order of bit
53 * values progressively decreases as the octet number increases.
54 * The least significant bit of the field is represented by the
55 * lowest numbered bit of the highest numbered octet of the field.
56 *
57 * which sure sounds little-endian.
58 *
59 * [
60 * Later comment:
61 * Actually: To me. the above reads as being BIG_ENDIAN.
62 * IOW: if bytes are numbered from 0 to n, then the n'th byte
63 * ("highest numbered octet") has the least significant bit.
64 * ]
65 *
66 * However, for some not-entirely-obvious reason, BSSGP_LITTLE_ENDIAN, which
67 * was passed to proto_tree_add_item() as the byte-order argument, was
68 * defined as FALSE - which meant big-endian.
69 *
70 * For now, we'll use ENC_BIG_ENDIAN, now that we have ENC_BIG_ENDIAN and
71 * REP_LITTLE_ENDIAN definitions.
