Francisco 327687cbc2 nr,sched: auto clear HARQs that exceeded maxretx, after the feedback has been processed 3 years ago
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.
