epan/dissectors/packet-umts_fp.c
* Added mac subdissector (MAC) call to HSDSCH TYPE2 frames
epan/dissectors/packet-umts_mac.c
* Added support for HSDSCH TYPE2 frames by means of
not nibble-shifting (4 bits) the SDU if MAC-ehs is used
epan/dissectors/packet-rlc.c
* Added support for "Use special value of the HE field" (3gpp 25.332-7a0
9.2.2.7) commonly used for Release 7 HSDPA.
REMARK: although the specification mandates that the
special value is only allowed when activated by higher
layers (RRC), it is interpreted unconditionally. We assume
this is OK, because a different use in future specifications
is very unlikely.
epan/dissectors/packet-fp_hint.c
* Added decoding of MAC-ehs indicator for HSDSCH frames
* Bumped fpi->release from 6 to 7 to enable proper
HSDSCH TYPE2 frame decoding in the UTMS MAC parser.
In general, this appears not to affect decoding
of (conformant) FP frames of pevious releases.
