- according to 5.3.7.4 of TS 38.331

- remove PDCP reestablishment for DRBs from RRCReestablishment message generation
- do PDCP reestablishment and CUUP notification calls after reception or RRCReestablishmentComplete
- this is necessary to make it consistent with the RRCReconfiguration message that contains
  RadioBearerConfig with the list of bearers to add/release
  which is followed by PDCP re-establishment at UE

- SRB1 shall be re-established at the time of RRCReestablishmentRequest
  according to 5.3.7.4 of 3GPP TS 38.331
- SRB2 shall be re-established when creating srb-ToAddModList
  according to 5.3.5.6.3 of 3GPP TS 38.331

These functions enables (un)deployment of the OAI CN v2.0.1, increase
reliability and speedup overall CN (un)deployment compared to current
implementation.

Use "--wait" helm option to wait for deployment/undeployment of the CN.
Wait for pods to be in a ready state before marking the release as
successful. If not deployed/undeployed before timeout, marked as
unsuccessful.

Hardcode path for OC CN5G deployment/undeployment

- Remove unused AmariUE config file, replace by new one - for PLMN 00102
- Change frequency of AW2S pipeline - Move center frequency by 40 MHz to avoid interferency with other setups
in the lab. Set center frequency to ~ 3450 MHz.

- change testcase IDs to get all logs

The absslot_tx overflow issue observed during integration testing of AW2S
RU with GPS as the source for the clock synchronization. Causes the gNB
not to start the TX thread and stops the processing.

Also, the check for clang is done in CMakeLists.txt; sleep is useless

Reset all the circular buffer to zero; this ensures that we cannot read
uninitialized data. Since this is RFsimulator, performance is not a
problem here either (and zeroing out happens only once).

Memsan complains that uninitialized reads originate because of these
warnings. Most of the corresponding variables are actually read into
through by libconfig; nevertheless, initializing them should not have a
bad side-effect (because the initialized value is overwritten).

Fix clang warning

  warning: use of GNU old-style field designator extension [-Wgnu-designator]

We access G_N at indexes that are not necessarily 32-byte aligned,
leading to segfaults. Use simde_mm256_loadu_si256() to load from memory
at an unaligned memory address to avoid the segfault.

Discovered using clang; it is unclear why gcc did not encounter the same
segfault.

-rdynamic is necessary for clang as well to properly link shared
executables. Add furthermore an option to ignore unused command line
arguments, to suppress warning

  clang: warning: argument unused during compilation: '-rdynamic' [-Wunused-command-line-argument]

This is likely because -rdynamic is only relevant for the linker, but
the corresponding option add_link_options() is only available starting
cmake 3.13, while we are still at 3.12 (for Ubuntu 18, to my
understanding).

After the recent update of matix, collected logs contain color codes
and we did not find the way to switch them completely off.
Replacement of "docker compose logs" by "docker logs" resolves this
issue. This commit includes changes related to "docker logs" usage.

- Update the configuration for benetel 650 and 550 for new firmware version
- Remove the old firmware configuration file and description in the document
- Add a new RU configuration section
- Add How to get support from the OAI Community to clarify the support procedure.

Include "best practices" on how to ask questions.
