 *
 * An encapsulating dissector that knows which radio port a frame came
 * from (KISS) stores GUINT_TO_POINTER(port + 1) under this key just
 * before calling the AX.25 dissector. The AX.25 dissector consumes and
 * removes it, and uses the port as part of the link (conversation) key.
 *
 * The data pointer isn't used for this because the AX.25 dissector is
 * also reached through wtap_encap and ip.proto, whose callers pass data
 * pointers of their own.

 * They are still dissected as before; AX.25 only leaves them out where
 * the length of the frame matters.
