Pedro Alvarez 476f9e1156 Changed logger initialization in RLC AM entities 2021-11-12 22:41:37 +00:00
Pedro Alvarez 022c51493b Refactored RLC AM NR/LTE Rx and Tx entities to use a rlc_am_base_rx/tx class. 
This was done to make it easier to share entity specific code between LTE and NR.
This removes the previously used templates.
 2021-11-12 22:41:37 +00:00
Pedro Alvarez b15f63f32f Added an RLC AM base class to avoid code duplication in the RLC AM NR entity. 
This class is based on a template that receives as argument the
rlc_am_*_tx/rx entities, so that those are different for LTE and NR.

Moved code from rlc_am_lte/nr entities so that they use the new base class.

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

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.
