- Why I did it
The field 'subport' represents the index of the split port within a physical port. For example, if a port is split into 4, the subport of the first logical port is 1, the subport of the second logical port is 2, and so on.
In xcvrd, the CMIS manager uses the subport to calculate the lane mask, which is used to control the data path per lane. In Nvidia platform, the subport is missing and is always set to 0. According to the xcvrd code, when subport=0, it will always correspond to the first logical port. Therefore, if we shut down any logical port that is not the first one, we will see the operational status of the first logical port also becomes down.
This PR aims to add the subport field to CONFIG DB and prevent such scenarios. This is applicable only for static default breakout mode. For DPB, subport calculation will happen on the fly (changes are not in Sonic yet).
(Subport HLD: HLD of subport: [link to the HLD document])
- How I did it
I have added the 'subport' field to all relevant Nvidia hwsku.json files (minigraph generation is based on them). Additionally, I introduced the new 'subport' field to portconfig.py, so that sonic-cfggen will be able to generate the minigraph with it. In this file, I also fixed an error that caused all attributes from hwsku.json to be applied only to the first logical ports associated with a physical port.
Furthermore, I updated hwsku_json_checker to include the new field and applied a fix to the sample_hwsku.json file. sample_hwsku.json is the file that sonic-config-engine's unit tests rely on for its tests. Previously, it only included attributes for the first logical port of a split physical port. For example, if Ethernet4, a 4-lane port, was split into 2 ports, then sample_hwsku.json included only the entry for Ethernet4, with no entry for Ethernet6. This misalignment with the structure of other hwsku.json files has been corrected as well.
- How to verify it
Ensure that each logical port has the correct value of 'subport' in CONFIG DB, and that shutting down a logical port affects only that port and not other ports in the split.

These changes adjust Nokia IXR7250 thermal sensor logging thresholds.
Why I did it
To modify the thermal sensor logging thresholds used on LC and Supervisor.
How I did it
Modified the JSON based thermal logging thresholds used to determine when to log current high sensor temperature and hottest sensor margin fluctuations.
How to verify it
Verify that syslog messages indicating current (high) temperature and margin values are only logged when these respective values fluctuate by at least 5 degrees.
This change of removing hwsku.json is to correct the port index for
sfp ports (Ethernet0, Ethernet1, Ethernet2, Ethernet3) by using
port_config.ini, which should be '1, 2, 3, 4'. We could not do it
with hwsku.json, as it is defined as '5, 5, 5, 5' by platform.json
for the breakout_mode 1x40G[10G].
For 40G optics there is SAI handling of T0 facing ports to be set with SR4 type and unreliable los set for a fixed set of ports. For this property to be invoked the requirement is set
phy_unlos_msft=1 in config.bcm.
This change is to meet the requirement and once this property is set, the los/interface type settings is applied by SAI on the required ports.
Why I did it
For Arista-7060CX-32S-Q32 T1, 40G ports RX_ERR minimalization during connected device reboot
can be achieved by turning on Unreliable LOS and SR4 media_type for all ports which are connected to T0.
The property phy_unlos_msft=1 is to exclusively enable this property.

These changes, in conjunction with NDK version >= 22.9.17 address the thermal logging issues discussed at Nokia-ION/ndk#27. While the changes contained at this PR do not require coupling to NDK version >= 22.9.17, thermal logging enhancements will not be available without updated NDK >= 22.9.17. Thus, coupling with NDK >=22.9.17 is preferred and recommended.
Why I did it
To address thermal logging deficiencies.

How I did it
The following changes are included:
Threshold configuration values are provided in the associated device data .json files. There is also a change included to better handle the condition where an SFP module read fails.
Modify the module.py reboot to support reboot linecard from Supervisor
- Modify reboot to call _reboot_imm for single IMM card reboot
- Add log to the ndk_cmd to log the operation of "reboot-linecard" and "shutdown/satrtup the sfm"
Add new nokia_cmd set command and modify show ndk-status output
- Add a new function reboot_imm() to nokia_common.py to support reboot a single IMM slot from CPM
- Added new command: nokia_cmd set reboot-linecard <slot> [forece] for CPM
- Append a new column "RebootStatus" at the end of output of "nokia_cmd show ndk-status"
- Provide ability for IMM to disable all transceiver module TX at reboot time
- Remove defunct xcvr-resync service
Why I did it
When Supervisor card is rebooted by using PMON API, it takes about 90 seconds to trigger the shutdown in down path. At this time linecards have been up. This delays linecards database initialization which is trying to PING/PONG the database-chassis. To address this issue, we modified the NDK to use the system call with "sudo reboot" when the request is from PMON API on Supervisor case. The NDK version is 22.9.20 and greater. This new NDK requires this modifcaiton of platform_reboot to work with.

Microsoft ADO (number only): 26365734
How I did it
Modify the platform_reboot In Supervisor not to reboot all IMMs since it has been done in the function reboot() in module.py. Also handle the reboot-cause.txt for on the Supervisor when the reboot is request from PMON API.

CS00012320965 - SAI9.2: iBGP doesn't work due to SA_EQUALS_DA trap
If SA_EQUALS_DA trap is enabled iBGP won't work as the Ethernet-IB0 ports are expected to get packets with SA==DA.
In the VOQ chassis design, for outgoing control plane packets, the packets goes the recycle port for routing, therefore the dmac of the packet should be the asic router mac. The source mac is assigned by the kernel, so it is also the asic router mac.

sonic-mgmt xoff test was failing for [100g,120km]. Needed to update total headroom pool size when 100G line card is used as T2 uplink.
This size was calculated assuming 100g is used for downlink so cable length was 2km whereas it can also be used for uplink (cable length - 120km). so we need to do calculation based on 120km not 2km. Although it will be some wastage for 2km scenario but it should cover both cases.
