Hi,
the radius avp specific dissectors registered with
radius_register_avp_dissector are broken. The problem is that they are
registered before the dictionary loads. The loading of the dictionary then
replaces the previously added avps in the g_hash_table.
This functionality is used by packet-gtp.c, packet-radius_packetcable.c and
from what i found it packet-radius.c itself.
I have used the following patch to solve this (as i am implementing a
ascend-data-filter specific dissector right now).
I am unshure this is the right way as the order of init is not fixed as i
understand it. Probably fixing dictionary loading to not overwrite the full avp
but rather copying the dissector over would be more robust.
