Hi All!

While looking at a wireshark trace (with the newly discovered wireshark system
information dissector, for which I'll submit a patch to wireshark later
tonight), I just realized that in SI1 we still shend a Cell Allocation of a
hardcoded ARFCN 123.

So unless you run in GSM900 and you use ARFCN 123, the SI1 content will
disagree with the actual radio carrier.

This is likely to cause confusion with at least some phones.

We already have code to generate the channel lists inside SI messages, but this
code is so far not used in the master branch.

So this is just a reminder "There is a known Issue".  If you want to experiment
with a supposed fix for it, try using the system_information branch.

Regards,
	Harald
