Attempt to detect IPA header over UDP and handle it correctly
Build Information:
This is from the latest svn version.
--
The current implementation assumes that the IPA protocol header is three byte.
This is true for TCP but not for packets sent over UDP. The difference can be
seen in OpenBSC's ipaccess-find utility sending a broadcast packet with a IPA
payload.
The proposed patch is based on the approach of the IPA dissectors and works by
checking if the specified length + 1 is the length of the payload. This appears
to work.
