Wireshark-bugs: [Wireshark-bugs] [Bug 10323] MIPv6 Service Selection Identifier parse error

Comment # 2 on bug 10323 from
Thanks for your comment Pascal.

The spec that you refer to looks to be the spec for APN in case of LTE.

However, we are referring to service selection field in PMIPv6 messages which
use RFC 5149 as reference.

In the RFC also, the service selection is defined as follows:

"Identifier: A variable-length encoded service identifier string
      used to identify the requested service.  The identifier string
      length is between 1 and 255 octets.  This specification allows
      international identifier strings that are based on the use of
      Unicode characters, encoded as UTF-8 [3], and formatted using
      Normalization Form KC (NFKC) as specified in [4].

      'ims', 'voip', and 'voip.companyxyz.example.com' are valid
      examples of Service Selection option Identifiers."

Here, there is no additional octet at the beginning of the identifier field.

Please correct me if I'm mistaken, but I believe the PBU is sent as per RFC5149
and the wireshark code also refers to this RFC(in the comments for the
function).
