Hi all,

I've been looking at receiving CBCH traffic (where I live, 226-01
broadcasts a geographical area name with each cell).

Patches 1/1 and 1/2 are small fixes for the layer23 system information
parser, for storing the required CBCH channel description and mobile
allocation info.

I'll also reply with WIP patches for a small CBCH sniffing l23 app, and
for decoding CBCH in Wireshark.  The latter is a quick hack job, as it
only decodes the first block, and it's bodged onto the LAPDm dissector.

Also a question:  what would be the best place to integrate CBCH
handling into osmocom-bb?  I'm guessing host/layer23/src/common/lapdm.c
would handle block reassembly, then send CBS frames up the stack.  Would
any existing messages fit the bill (RSL_MT_UNIT_DATA_IND?) or should we
add a new one?
