Yes, that's also the reason why I already acked this patch. We can
solve this later a little bit cleaner if necessary.

My patch that takes care of the orphaned packets in x25_receive_data()
has again a dependency on other patches, especially the patch to
configure the neighbor parameters (DCE/DTE, number of channels etc.),
which I already sent before but still have to revise.

Unfortunately I have only limited time for this topic, so I am not as
fast as some people would wish. Sorry for that.
