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.

Carlo Galiotto fb75cbaadc rrc: disable MAC bearers when RNTI gets updated
When the RRC handles the C-RNTI CE to update the RNTI, all the bearers
associated with the new RNTI (that will no longer be used) need to be disabled.
This commit implements this.
