 * TS 48.018 V6.6.0 (2004-11) says, of information elements:

 *    Refer to General Structure Of The Information Elements/3GPP TS 48.016.
 *
 * TS 48.016 V9.0.0 (2010-02), in that section, says, of information elements:
 *
 *    When a field extends over more than one octet, the order of bit
 *    values progressively decreases as the octet number increases.
 *    The least significant bit of the field is represented by the
 *    lowest numbered bit of the highest numbered octet of the field.
 *
 * which sure sounds little-endian.
 *
 * [
 * Later comment:
 * Actually: To me. the above reads as being BIG_ENDIAN.
 *  IOW: if bytes are numbered from 0 to n, then the n'th byte
 *       ("highest numbered octet") has the least significant bit.
 * ]
 *
 * However, for some not-entirely-obvious reason, BSSGP_LITTLE_ENDIAN, which
 * was passed to proto_tree_add_item() as the byte-order argument, was
 * defined as FALSE - which meant big-endian.
 *
 * For now, we'll use ENC_BIG_ENDIAN, now that we have ENC_BIG_ENDIAN and
 * REP_LITTLE_ENDIAN definitions.
