Pedro Alvarez f9a2850d74 gnb,ngap: Added interface so the NGAP can pass a NAS message to the RRC
upon starting the RRC Security Mode command. This allows the gNB to
pass this message only after the SM procedure is complete.

Also made sure that the RRC notifies the NGAP upon the end of the
reconfiguration procedure, to make sure that the NGAP sends the UE
context setup response.

Francisco ffc1ea5c86 nr,gnb,phy: decoupled gnb and enb phy config structs by moving them to separate files 3 years ago
Pedro Alvarez 4e1c713c14 rlc_am_nr: Enabled sending NACKs on status PDUs
- Added some logic to only poll when PDU_WITHOUT_POLL > PollPDU
  - Fixed initalization of t-Reassembly
  - Fixed a bug in the packing of the status buffer.
Nacks now work for a single lost PDU.

Andre Puschmann 3eb1862ab9 gnb_interface: reduce MAX_GRANTS to 4

Xavier Arteaga ebab12403f
Asynchronous NR PHY configuration (#3527)
* Fix a race condition when accessing the NR PHY cfg by the RRC and phy workers.
Rework how the phy cfg is handled, now workers have their own copy that gets updated after a reconfig moving it out of the state class.

* Default initialize sf_len member in sf_worker for consistency.

* Asynchronous NR PHY configuration

* Fix compilation

* Corrected method override and fix unitialised value

* Added carrier equal comparison to avoid aligment byte padding comparison

with scheduler results.

Pedro Alvarez fbcffb84bd Check if RLC is suspended before transmiting PDCP SDU.
This was done to avoid integrity issues, when the UE's RRC erroneously sent
measurement reports while the re-establishment was already in progress.

As errously sending PDCP PDUs on DRBs can cause issues as well, this was
disabled too.
