Why I did it
Zebra core sometimes seen during config reload. Series of route-map deletions and then re-adds, and this triggers the hash table to realloc to grow to a larger size, then subsuquent route-map operations will be against a corrupted hash table.
Issue is seen when we have BFD Enable on Static Route table we see Static route-map being created/deleted based on bfd session state. However issue itself is very generic from FRR perspective.
Thie issue has detailed core info sonic-net/sonic-frr#37 . This PR fixes this issue.

How I did it
This fix is already in Master frr/8.2.5. Porting this fix to 202205 branch to address this Zebra core.
sonic-net/sonic-frr@5f503e5
Solution:
The whole purpose of the delay of deletion and the storage of the route-map is to allow the using protocol the ability to process the route-map at a later time while still retaining the route-map name( for more efficient reprocessing ). The problem exists because we are keeping multiple copies of deletion events that are indistinguishable from each other causing hash havoc.
How to verify it
Verified running sonic-mgmt test, doing multiple config reloads.
chassis-packet: Update arp_update script for FAILED and STALE check (#16311)
1. Fixing an issue with FAILED entry resolution retry.
Neighbor entries in arp table may sometimes enter a FAILED state when the far end is down and reports the state as follows:
2603:10e2:400:3::1 dev PortChannel19 router FAILED
While the arp_update script handles the entries for FAILED in the following format, the above was not handled due to the token location (extra router keyword at index 4):
2603:10e2:400:3::1 dev PortChannel19 FAILED
The former format may appear if an arp resolution is tried on a link that is known but the far end goes down, e.g., pinging a STALE entry while the far end is down.
2. Refreshing STALE entries to make sure the far end is reachable.
STALE entries for some backend ports may appear in chassis-packet when no traffic is received for a while on the port. When the far end goes down, it is expected for BFD to stop sending packets on the session for which the far end is not reachable. But as the entry is known as stale, on the Cisco chassis, BFD keeps sending packets. Refreshing the stale entry will keep active links as reachable in the neighbor table while the entries for the far end down will enter a failed state. FAILED state entries will be retired and entered reachable when far end comes back up.
* [minigraph] remove number of lanes check for changing speed from 400G to 100G and set speed setting before lane reconfiguration (#15721)
8111 800G interface, split to 2x400G (each has 4 lanes) fails to change interface speed from 400G to 100G during deploy mg. In minigraph.xml, the interface speed configuration is good, but fails to generate the right value to config_db.json.
In order to support this SKU the speed transitioning should support both 4 lanes and 8 lanes in the port_config.ini.
Why I did it
before this change for a 400G to 100G transition, in all cases except when lanes are 8, we would continue and the line
ports.setdefault(port_name, {})['speed'] = port_speed_png[port_name]
would not be executed, hence the default speed will never be set for a case and config_db will not be updated,
where speed is transitioning from 400G to 100G or 40G, but lanes are not equal to 8.
In order for those cases to pass where lanes are not specifically 8, we need the change

We now disable the i801 driver interrupt and instead enable polling

This fix is NOT applicable for ARM based platforms. Applicable only for intel based platforms:-

- Why I did it
Commit sonic-net/sonic-platform-daemons@153ea47 changed SfpStateUpdateTask from Process to Thread. In this commit, it raises an exception in SfpStateUpdateTask to make shutdown flow fast. But it does not work on Nvidia platform as Nvidia platform is passing timeout parameter of get_change_event to select. Linux select function can not be interrupted by a Python exception. There is no such issue on Nvidia platform before that commit. However, in order to comply with the commit and make shutdown flow fast, we decided to change Nvidia platform API implementation.
To fix issue #13591.
- How I did it
The select call in get_change_event should use no more than 1 second as timeout parameter.
Outside the select call, add a while loop to make sure timeout parameter of get_change_event work as expected

The original PR will disable intel idle driver but it cannot limit the max c-state to 1 due to system will fall back to acpi idle driver.
Currently intel_idle.max_cstate=0 is already present, which will disable intel idle driver. With the added option, common idle driver will be disabled as well, so there will not be idle management. This is to prevent a bug that can be triggered by idle instruction on intel platform.

- Why I did it
watchdogutil uses platform API watchdog instance to control/query watchdog status. In Nvidia watchdog status, it caches "armed" status in a object member "WatchdogImplBase.armed". This is not working for CLI infrastructure because each CLI will create a new watchdog instance, the status cached in previous instance will totally lose. Consider following commands:
admin@sonic:~$ sudo watchdogutil arm -s 100 =====> watchdog instance1, armed=True
Watchdog armed for 100 seconds
admin@sonic:~$ sudo watchdogutil status ======> watchdog instance2, armed=False
Status: Unarmed
admin@sonic:~$ sudo watchdogutil disarm =======> watchdog instance3, armed=False
Failed to disarm Watchdog
