Do not directly send data from inside the mgcp_protocol.c
implementation. Instead allocate and return a struct msgb*. The
caller can then either wrap that into the IPA protcol or directly
send it over the UDP socket.
* Call a callback when the endpoint was created, modified or deleted. This
can be used by the BSC MUX to send a MGCP packet over TCP to the right
the BSC to allocate the endpoint there with the right data, or it can be
used in the BSC to send the right commands to the BTS.
* Separate main process and protocol handling into two parts.
* Change the protocol handling to work with UDP and TCP connection
* This will allow to speak MGCP over TCP between the BSC MUX and
the real BSC.
Some NM attributes are defined differently depending on
the BTS type. Having one big nm_att_tlvdef[] table for
all BTS types is no longer sufficient. This patch
* introduces 'struct gsm_bts_model' to describe a BTS model
* adds definitions of gsm_bts_model for BS-11 and nanoBTS
* changes the abis_nm_tlv_parse() function: include a bts pointer
Whether this function changes the set or the work value depends on your
type of login. In FACTORY login it changes the set value, in FIELD login
it changes the work value (which is what is used by the BS11 to tune the
frequency).
This is useful information to know and actually fixes a segfault
in rllp.c where lchan is accessed even tough it could be NULL in
case of failure.

Theses will be useful to know if we can reuse the tuples or if
we should renew. The 'issued' is currently purely informative.

This returns true if the gsm_nm_state can be considered 'running'.
Note that we also accept availability==0xff (which is a code for
no value) because according to 12.21 it is perfectly valid.

Thise two functions are interfacing with the 04.08 layer 3 to
determine if a particular message should be handled inside
the OpenBSC layer 3, or if it should be handled in the silent call
handler.
* On start the vty code will call the abis_nm method and this
will set the administrative state to unlock/lock
* During startup the BTS will report its state as well and would
possible overwrite the set administrative. We are only going
to update the administrative if it was 0 before. This appears
to work on all of my tests. In case this will not be the case
for others we will have to split the administrative into two
sets one for the BTS and one for the BSC.
* Do not issue the restart right aways if we have OML IP or
software load in the queue (hint, we need a real queue of operations
to carry out... with one big state machine)
* Change the signal_data of ipacc ACK/NACK to contain the msg type
and the bts pointer.
* Issue a restart for software load and OML and use the BTS pointer
we got out of the new signal data.
* text3 seems to be a version as the text content starts
with a 'v'
* move the sdp_firmware into the ipaccess.h and declare
the function. The headers are returned through a list.
In many cases we actually want a name / unique ID for the lchan,
not just for the on-air timeslot... especially in SDCCH/8 case,
where 8 SDCCHs share one timeslot...
When we allocate a channel, we send the RSL CHAN ACT REQ and wait until we get
a CHAN ACT ACK. Only the ACK will change the state, so there is a race where
we allocate that same channel to a different channel request before we get
the ACT ACK.
Introducing a new ACT_REQ state resolves this issue.
