The attached patch adds the following enhancements to the UMTS RLC dissector
(as specified in 3GPP 25.322 v9.2.0):
- UDP framing protocol to allow dissection of RLC PDUs over UDP (like what is
done for LTE MAC/RLC/PDCP protocols)
- 15 bits Length Indicator support (both with variable and fixed LI size)
- Poll type SUFI
- enhanced dissection of LIST, Relative List and Bitmap SUFI
- dissection of Reset and Reset Ack Control PDU
- an option to decode RLC headers only
- an option to skip SDU reassembly
