Pedro Alvarez 6d55560256 lib,rlc_am_nr: check if ACK SN is within rx_window. Stop
t-PollRetransmit only if status report is not ignored
3 years ago
Pedro Alvarez c457132570 lib,rlc_am_nr: avoid if that would always be true when checking the
out-of-order ACK. Check ACK_SN instead of stop SN with Tx_Next_Ack

Robert Falkenberg 489259dc78 lib,rlc_am_nr: extend status PDU struct with self-contained packed size info
This change refactors the rlc_am_nr_status_pdu_t from a simple
container into a class with integrated counter of the packed size.
As this depends on the SN length, the SN length must be passed
via constructor.

Robert Falkenberg d8cb4ec700 lib,rlc_am_nr: detect gaps in sequence of received SDU segments

"there is at least one missing byte segment [...] before
the last byte of all received segments of this SDU"

Pedro Alvarez 12f440145d lib,rlc_am_nr: changed build_retx_pdu_without_segmentation to pass retx
info by copy. This is to avoid accidently using retx info by reference
after pop'ing the retx from the queue.

behaviour between RETX and non-RETX PDUs.

Robert Falkenberg 5bb6cdec1e lib,rlc_am_nr: use std:vector for nacks in rlc_am_nr_status_pdu_t
- Also create tx_status a member to avoid frequent allocations
for each created PDU.

- Remove unused member nack_range from rlc_am_nr_status_pdu_t.
