#### Why I did it
When a kernel crash occurs, the system will reboot to the kdump capture kernel if kdump is enabled (`config kdump enable`). In the kdump capture boot, it only stores the crash information, and then reboot the system to a normal boot.
In this boot, no SONiC service is started but it invokes `reboot` which is actually the SONiC reboot that depends on SONiC services. There is a logic to skip all SONiC stuff and invoke platform reboot in SONiC reboot to avoid issues.
However, on Nvidia platforms, the platform reboot still depends on SONiC services, which can cause issues.
So, the Debian reboot is called directly in platform reboot if it is invoked from the kdump capture boot.
#### How I did it
Manual test
Added support data for fabric monitoring in CONFIG_DB
The CONFIG_DB now has the FABRIC_MONITOR|FABRIC_MONITOR_DATA table for default value for fabric port monitoring. An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_MONITOR|FABRIC_MONITOR_DATA"
{'monErrThreshCrcCells': '1', 'monErrThreshRxCells': '61035156', 'monPollThreshIsolation': '1', 'monPollThreshRecovery': '8'}
The CONFIG_DB now also has a table for each fabric port for its isolate status.
An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_PORT|Fabric20"
{'alias': 'Fabric20', 'isolateStatus': 'False', 'lanes': '20'}

When reboot the chassis by issuing "sudo reboot" on Supervisor card. The internal midplane communication xe0 should be shutdown to avoid double reboot on the linecard.
Added a udev link rule to disable the autoneg on AMD xgbe port Xe0 and Xe1 and make the setting in sync with the peer Broadcom greyhound ports.
How I did it
Modify the Nokia-7250IXRE specific reboot script on the Supervisor card to shutdown the internal interface xe0. Also move reboot linecard code to the top of the script to make sure the notification has been send to Linecard before shutdown the xe0 interface.
Introduced a new rule 80-net-by-driver.link to disable the autoneg on the AMD size. This change requires the latest NDK which contains the change to set the autoneg on the xe0 and xe1 port on the Greyhound.

Support DSCP remapping in dual ToR topo on T0 switch for SKU Mellanox-SN4600c-C64, Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8.
- How I did it
Regarding buffer settings, originally, there are two lossless PGs and queues 3, 4. In dual ToR scenario, the lossless traffic from the leaf switch to the uplink of the ToR switch can be bounced back.
To avoid PFC deadlock, we need to map the bounce-back lossless traffic to different PGs and queues. Therefore, 2 additional lossless PGs and queues are allocated on uplink ports on ToR switches.
On uplink ports, map DSCP 2/6 to TC 2/6 respectively
On downlink ports, both DSCP 2/6 are still mapped to TC 1
Buffer adjusted according to the ports information:
Mellanox-SN4600c-C64:
56 downlinks 50G + 8 uplinks 100G
Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8:
