This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (077e4d2113d0f7ae8e36337b33eba352555df41a)
\
N -- N -- N (3b4ce09989878f428a23e18f0720f856dbd1db57)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

host/trxcon/scheduler: store BSIC in trx_instance
We need to know BSIC value, before sending RACH requests.
So, let's store it in trx_instance and update as soon as
the first SCH burst is received after L1CTL_FBSB_REQ.

host/trxcon/scheduler: modify trx_lchan_tx_func definition
Initially, it was assumed that TX lchan handler will only
compose a burst and return a pointer to the buffer. A burst
itself could be sent somewhere outside, e.g. by caller.
It would be better to send bursts exactly from handler, because
in this case it isn't required to have an external buffer.

target/fake_trx: initial release of virtual transceiver
This is a set of tools for creating a virtual Um-interface between
OsmocomBB and OsmoBTS. It may be extremely useful for testing and
development of GSM stack, including both sides (MS and BTS). This
software implements OsmoTRX (Osmocom's fork of OpenBTS transceiver)
style clock (CLCK), control (CTRL) and data interfaces. So, OsmoBTS
source code doesn't require any modifications, while for OsmocomBB
you will need to use a new application - trxcon, which can be found
in the 'fixeria/sdr_phy' branch until one is merged to master.
Brief description of available applications:
- fake_trx.py - main application, that allows to connect both
OsmocomBB and OsmoBTS without actual RF hardware. Currently
only a single MS may work with a single BTS.
- clck_gen.py - a peripheral tool aimed to emulate TDMA frame
clock generator. Could be used for testing and clock
synchronization of multiple applications. It should be noted,
that one relays on generic system timer (via Python), so
a random clock jitter takes place.
- ctrl_cmd.py - another peripheral tool, which could be used
for sending CTRL commands directly in manual mode, and also
for application fuzzing.
