Andre Puschmann 46d8ed8742 enb,rrc: delay UE release after RLC maxRetx
this fixes the eNB behaviour when RLC signals maxRetx reached.
By directly releasing the UE, we ignore the fact that the UE
could still have the reestablishment counters running, so
could attempt a reestablishment, which would result in a reject
because we would have destroyed the UE context too early.

this patch delays the removal of the UE to wait at least
until the reestablishment timers are expired.

RLC failure to deliver notifications and discard timer limits to 1500ms (#2368)
* Added interfaces for the RLC to notify the PDCP of failure to transmit
SDU

* Limit discard timer to 1500ms, to avoid issues of lingering SDUs in the undeliverd_sdus_queue.

* Fix bug in early exit of notify_delivery and notify_failure

* fix compilation issue in rlc-pdcp notification

Francisco 3265d940ec remove byte buffer pool cached member variables as they are unnecessary now. 4 years ago
Pedro Alvarez de90b4753f Added the ability of the RLC AM to notify the PDCP of the acknowledged
PDCP PDUs. This includes:

- Modifying the byte_buffer_t to include PDCP SN meta-data. This way,
  the RLC can keep track of the ack'ed bytes for a specific PDCP PDU.
- Added in the RLC an `undelivered_sdu_info queue`, to keep track of the
  amount of ack'ed bytes and the total size of the PDCP PDU,
  so the RLC can know when delivery is finished.
- Added an interface between the PDCP and the RLC so that the RLC can
  notify the PDCP when it receives an ack from the status PDUs. The RLC
  passes to the PDCP a vector of all the ack'ed pdus in a rx'ed status PDU.
- Added some tests to the notify functionality. This includes some tests
  where the PDUs are acked imediatly, and one test where the PDU is
  retx'ed.

Andre Puschmann 8e13f04684 mac_pcap: refactor MAC PCAP and include NR RAT into same object
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.

This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.

this patch addresses the last open point of #2160
