This reverts commit 28411652.

The problem is that (1) we don't really support multi-homing, but (2) on
some system, if the other IP addresses that the operating system
considers part of the multi-homed connection are HEARTBEAT'ed (e.g.,
docker), they answer with SCTP ABORT, which breaks the entire
connection.

In other words, force single-homing by binding. For F1-U uses, another
option will be introduced that allows to bind to a separate interface
for F1-U (separate from F1-C), if necessary.

Simplification of the code by replacing iperf_opt by target_bitrate (returned from Iperf_ComputeModifiedBW) - no need to repeat the steps to retrieve information about requested bitrate from iperf_opt. Compute iperf bitrate performance as receiver bitrate over requested (target) bitrate.
Fix an issue with misdetection of missing report line - "result" was defined 2x in the function. With this MR, result can be only None or stores output of re.search() for matching the report line pattern, which ensure proper detection of the report line as well as presence off all required components in the report line.

Sender bitrate is not always equal to the requested bitrate (set by "-b" iperf option) in iperf3 (v3.9) UDP tests, so we have to compture bitrate performance of UDP iperf3 test as receiver over requested bitrate. Bitrate performance then express percentage of requested bitrate, which is received on the receiver side.

For iperf3 (version 3.9) UDP, sender bitrate is not always equal to requested bitrate (defined by '-b' option). We need to retrieve information about the requsted bitrate from iperf command line options specified for each UDP testcase. This parameter is then used in UDP analysis functions for proper evaluation of the test results.

Prior to this commit, it might happen that the gNB used TDA 0 (Start 0
len 13) for mixed slot, in which case the UE could not send msg3
(because a mixed slot has less than 13 symbols).

fixes the overflow issue in the PUCCH2 RX with 4+ RX antennas and 12+
bits (polar code format). The fix scales the polar decoding LLR
computation according to the number of RX antennas. The issue was clear
for 100 MHz 4 RX antennas. Even

  nr_pucchsim -s -5 -q 8 -P 2 -b 12 -R 273 -z4 -n1000

doesn't converge to 0 BLER with increasing SNR. The issue didn't appear
in CI because of the bandwidth and antenna count limitations.

- docker on CI machine avra was updated to version 26.0.0, which reports
  parameter "version" as obsolete
- this additional log causes fail of the container undeployment to stage

Closes: #775

We observe these asserts while running concurrent UL traffic on many
UEs:

  Assertion (crc->rnti == rx->rnti) failed!
  In handle_nr_ulsch() ../../../openair2/NR_PHY_INTERFACE/NR_IF_Module.c:193
  mis-match between CRC RNTI 7221 and RX RNTI 35cf

CRC and RX indication need to be pairwise for one UE, when here we have
each for different UE. However, investigation seemed to indicate that
both arrays for CRC and RX indication contained only one PDU; it seemed
the RNTI changed while writing the CRC/RX.indication messages in
nr_fill_indication().

In this patch, we change the logic to mark a ULSCH free AFTER calling
nr_fill_indication(). It is difficult to say if this makes the assertion
disappear, but preliminary tests did not exhibit the same failure
states.

Closes #773

- It is only a couple of bytes
- It hid a bug: if two preambles, L1_nr_prach_procedures() overwrote the
  preamble of the first with the second one

if we reduce, we will never do all rach indications. Go one-by-one
instead.

Move decision of Msg2 allocation time instant from instance we receive
RA indication (only containing preamble time information) to actual RA
scheduler (containing current DL slot time). This has the advantage:

- if Msg2 cannot be sent, we might try in a later slot
- no timing-based problems were a RACH.indication FAPI message might
  come late, we calculate a Msg2 frame/slot, but this instant has
  already passed in the DL scheduler
- no assumption about slot_ahead (an L1 constant)

The previous code calculated and verified an SSB index; I am not sure
this code is correct or used. I leave the function
ssb_index_from_prach() (hence the gcc attribute), but remove any checks.
Similarly, the beam association list might be wrong. I deleted the
corresponding code.
