GMM is the right term. MM state is already occupied.

The pcu sends us an already made up MAC-Block that contains the
paging request. pcu_sock.c is parsing this paging request
wrongly and fails silently, which results into a dropping of the
request.
This commit fixes the parsing problems.

The timer T3186, which is described in 3GPP TS 44.060, is using 3
bits of the si13 mac block. This requires special encoding. In the
case of T3186, the value is encoded by the formula: bits = t/500-1.
Our implementation uses the formula bits=t/500, which is incorrect.

In some rare cases the modem might send a xid indication that does
not contain anything except the version number field. The sgsn
ignors such SNDCP-XID indications by stripping the entire field
from the response. We found a modem in the wild that started to
act problematic when the empty SNDCP-XID was missing in the
response. This patch changes the XID negotiation behaviour in
a way that if a modem should send empty SNDCP-XID indications,
the reply will also contain an empty SNDCP-XID indication. Apart
from that the SNDCP-XID version number is now parsed and echoed
in the response. This ensures that we always reply with the version
number that the modem expects. (The version was 0 in all cases we
observed so far)

The pcu sock interface excidantly tells the PCU that MCS
coding schemes are enabled (allowed), even when no EGPRS
is configured. With this commit sending the MCS flags
will be explicitly avoided when EGPRS is not configured.

When the LLC-XID request is constructed the order of the elements
in the TLV structure is reversed. This is in theory not a problem,
but differs from what we know from our practical experience. This
commit fixes the problem.

Ericsson allows to attach a reference to immediate assignments. A
confirmation of the transmission is then sent back, but only containing
the reference, not the whole RLC packet.

ericsson can handle a reference at the end of the message which is used in
the confirm message. The confirm message is only sent if the trailer is present.

When using a BSC located PCU the BSC must understand PDCH requests.

The BSC-located PCU case looks to the PCU like a BTS-located PCU with
"direct PHY" access, i.e. the data related primitives are communicated
from the PCU directly towards the TRAU Frames or whatever transport
method is used between CCU and PCU.
In order to make the PCU believe that, we need to pass in a 'layer 1
handle'. As we don't use it, we can just pass any non-zero value and be
happy.

or not. Hide this behind the API.

The pcu interface required to support bsc co-located
pcu uses pcu_sock.c and its related header files as
a starting point.

This seems to be mandatory when an Ericsson RBS2000 uses a SuperChannel
as back-haul.

When the BTS is configured to use a SuperChannel and it is using a
unix domain socket based transport towards the L2TP daemon, then
we must instruct the L2TP daemon to instruct the SIU to change the Abis
Lower Transport Mode using the ALTCRQ / ALTCRP L2TP signalling.

When OM2000 has confirmed that a TS is started, call dyn_ts_init()
on the timeslot to start the processing for fully dynamic (osmocom
style) TCH/F_TCH/H_PDCH. This should in turn trigger the activation of
idle timeslots as PDCH until we want to allocate any of them for TCH/F
or TCH/H.

Ericsson has introduced a propritary format to issue the S13 BCCH
information. Normally the system info type field for SI13 would
be encoded as 0x28. Ericsson encodes that field as 0x02 and ads
a bcch mapping parameter, (IEI=F2) This patch sets the BCCH mapping
to 0x00 (=BCCH Normal) statically (0xF200)
The new constands are added to libosmocore, see commit:
