|
|
*
|
|
* 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.
