The testcase TC_meas_res_sign_tchX activates a traffic channel in
signalling mode and checks the RSL resulting measurement reports.
The CHANnel ACTIVation message sets "SDCCH" as "Channel rate and Type"
value. This is invalid, the "Channel Rate and Type" sould be set to "Half /
Full rate TCH Channel Lm / Bm" (while the speech or data indicator is
still set to "Signalling")

Calypso PHY (unlike trxcon) needs to be explicitly configured to
enable forwarding of the TCH traffic. Otherwise it's handled
internally by the DSP and routed to/from the built-in speaker/mic.

Otherwise the L1 (trxcon or Calypso PHY) would 'think' that we're
in signalling mode, and would not send us Bad Frame Indications.

A TRAFFIC.ind with 'num_biterr' > 0 or 'fire_crc' != 0 is still
a valid TCH frame - Bad Frame Indication. Let's relax those
parameters for tr_L1CTL_TRAFFIC_IND().

In osmocom-bb 'struct l1ctl_dm_est_req' is defined as follows:
struct l1ctl_dm_est_req {
uint8_t tsc;
uint8_t h;
union {
struct l1ctl_h0 h0;
struct l1ctl_h1 h1;
},
uint8_t tch_mode;
uint8_t audio_mode;
} __attribute__((packed));
so the overall size of the union is size of the biggest member:
sizeof(struct l1ctl_h0) is 2
sizeof(struct l1ctl_h1) is 132
Therefore we need to fix our definitions:
- introduce 'record L1ctlH0' (with padding),
- introduce 'union L1ctlH0H1':
- move hopping indicator to L1ctl{H0,H1},
- use it as 'TAG' in 'union L1ctlH0H1'.

When a RESET-ACK times out, the logs currently are indistinguishable between
BSSMAP and BSSMAP-LE. Add protocol naming for each RESET / RESET-ACK logging to
make sure the information does not need guesswork.
Example of a test failure shown in jenkins:
BSC_Tests.TC_unsol_ass_compl
Stacktrace
Timeout waiting for RESET-ACK after sending RESET
BSC_Tests.ttcn:8295 BSC_Tests control part
BSC_Tests.ttcn:4274 TC_unsol_ass_compl testcase
Nothing conveys that it is (presumably) the background *BSSMAP-LE* timeout
halting the test 5 seconds in, and not an A-interface failure.

If IP-SNS is not used we should wait for the RESET procedure to finish
before sending NS-ALIVE.
For IP-SNS start NS-ALIVE in both roles (sgsn and bss) and don't handle
NS-RESET.
Also unified the log messages a bit (received -> Rx).

This should not have been merged. It is an intermediate attempt to make the BSC
send the BSSMAP-LE RESET, which doesn't work because the BSC is not restarted
across test runs. I dropped the patch from my branch, while it remained on
gerrit accidentally; then someone else merged it without noticing that it was
no longer part of my lcs branch.
This reverts commit b2b3704d2a.

Both BSSMAP-LE and BSSMAP use the LCS Cause IE with identical definition. In
order to not add further dependencies from BSSMAP_Templates.ttcn to
BSSAP_LE_Types.ttcn to BSSLAP_Types.ttcn, duplicate the LCS Cause enum.

Expecting OsmoBSC to send a RESET to the SMLC implies that the virtual SMLC
stays quiet until a RESET is received. Add flag to configure RESET behavior of
BSSMAP-LE.

The BVC-RESET / BVC-RESEt-ACK follow a set of rules:
* Signaling BVCI=0 never has a CellId in BVC-RESET nor BVC-RESET-ACK
* Any BVC-RESET or BVC-RESET ack in BSS->SGSN direction must have CellID
* Any BVC-RESET or BVC-RESET ack in SGSN->BSS direction must NOT have CellID
Let's adjust our test expectations accordingly.
This will break tests against "latest", but the amount of work-arounds
needed in this code outweighs the benefit.

The existing BSSGP_Emulation is built around the assumption that every
instance of BSSGP_Emulation only servers one signaling-BVC and one
PTP-BVC. While this is true for osmo-pcu at this point (BTS-colocated
PCU), other BSS/PCU implementations differ.
In general, there can always be any number of PTP BVC (one per cell)
next to the signaling BVC (one per BSS). Let's represent this in
BSSGP_Emulation so we can create more comprehensive tests.

Both osmo-bts and osmo-pcu are switching to PCUIFv10 soon, so let's
use the new version by default. For older (latest) IUT versions
not supporting PCUIFv10, one would need to override this module
parameter in {BTS,PCU}_Tests.cfg.

This is a step to prepare the NS_Emulation for operating on top of
Frame Relay, not just UDP/IP. We replace the NS_CodecPort (mapping to
a IPL4asp) with a newly introduced NS_Provider_CT, specifically a
NS_Provider_IPL4_CT.
This change removes any IP specific bits from NS_Emulation and moves
it into the newly-created NS_ProvideR_IPL4.

Unlike osmo-pcu, osmo-bts does check length of the messages received
over the PCU interface, so I7a532d7abff8af354e40c5d706bb882efc6f905f
caused all the related test cases in ttcn3-bts-test to fail.
Reverting it is not a solution, because we cannot maintain different
padding attributes for two different protocol versions. Let's add
a wrapper function that would call enc_PCUIF_Message() and append
padding depending on the configured protocol version. In addition,
let's add a module parameter that would allow us to (optionally)
disable padding for ttcn3-pcu-test.
This change makes all broken PCUIF specific test cases pass.
