- removed going through all the harq processes before triggering nr_ue_ulsch_procedures in phy_procedures_nr_ue.c
- did not remove usage of MAX_HARQ_PROCESSES in init phase
- Enabled configuration for number of dl, ul harq processes in conf file

- If value 32 is configured , then IEs related to num harq processes and dci bits also configured in Bandwidth parts.
- MAX HARQ PROCESSES set to 32
- for PDSCH - default setting in OAI is 16, according to 3GPP rel17 38.331 these are the possible configs
- if no IES are defined then 8
- if nrofHARQ-ProcessesForPDSCH is defined then these values- {n2, n4, n6, n10, n12, n16}

- Modify CN deployment and termination functions to include namespace and path parameters.
- Update `Module_UE` class with new attributes for namespace and CN path.
- Integrate `cnID` for OC CN deployment and termination in `epc.py`.
- Extract `cn_id` from XML configurations for CN operations.
- Update XML files to include `cn_id` tag for 5G Core initialization and
termination. (Used in OAIUE and AW2S pipeline, for OC CN deployment. This change
will not affect other CN deployments.)
Create directories for gNB deployment with VVDN and Benetel550 RUs.
Each directory includes scripts for setting up and cleaning up the
host machine running the gNB.
Handle IPv6 (and IPv4v6) PDU sessions by correctly instructing
nas_config() to set up the interface with provided IP addresses.
Note that as of now, IPv6 PDU sessions have not been fully tested.
Remove a useless assert at the gNB; to my understanding the gNB does not
care about the IP session type (at least for IP), as it just
transparently tunnels the IP packets from/to GTP.
I added a comment in the code where to change to request a PDU session
different from IPv4. Currently it is hardcoded to IPv4, and it seems
that a default OAI 5GC config would reject a PDU session type different
from IPv4.
- Read interface flags before setting status to not inadvertently
overwrite existing flags
- Set interface flag point-to-point, remove multicast (I think a UE is
not supposed to send anywhere else than to the UPF, so it seems to not
make sense to declare the interface as multicast)
These rules & route are necessary to properly send packets on oaitun_ue1
interface:
1. This forces the packets coming from a subnet different than the UE's
subnet to go back through oaitun_ue1 rather than via what the default
route defined on the system (e.g., important if ping from the
internet arrives).
2. On machines setting net.ipv4.conf.oaitun_ue1.rp_filter=1 (e.g.
RHEL), this prevents that source filtering for packets coming back is
applied and those packets be dropped. By default, many hosts have
rp_filter=2, so no strict source filtering is applied, and it would
work; on others, this rule prevents source filter dropping.
Prior to this commit, there was a global variable baseNetAddress that
could be set independently through a setter and also through the
configuration module. This baseNetAddress (16 bits IPv4) would then be
complemented with two more bytes in nas_config().
However, this is counter-productive, as not only we have a global
variable that is avoidable (we can give the entire address to
nas_config() directly), but it also would not work with IPv6. Hence,
modify to give nas_config() the entire address. A follow-up commit will
add IPv6 support.
