When LLDP parameter tx-interval value is modified, there was no immediate PDU sent to peer to update the peer with the latest values. Due to this the update on peer happened only after the next PDU is sent which can cause a delay of upto 30 secs (default value).
* In the event of a kernel crash, we need to gather as much information
as possible to understand and identify the root cause of the crash.
Currently, the kernel does not provide much information, which make
kernel crash investigation difficult and time consuming.
Fortunately, there is a way in the kernel to provide more information
in the case of a kernel crash. kdump is a feature of the Linux kernel
that creates crash dumps in the event of a kernel crash. This PR
will add kermel kdump support.
An extension to the CLI utilities config and show is provided to
configure and manage kdump:
- enable / disable kdump functionality
- configure kdump (how many kernel crash logs can be saved, memory
allocated for capture kernel)
- view kernel crash logs
Fixed Makefile of FRR. Before we had issues after #3589:
- When you want to rebuild frr with new changes you get error "branch frr/7.1 is already exist".
- When your patch list is empty stg undo gives an error
* [sonic-cfggen] optimize execution time
a lot of template rendering causes switch to start longer because jinja2
needs to parse them. Introducing RedisBytecodeCache to store parsed buckets of
internal template bytecode to speedup same template rendering during start
* [sonic-cfggen] do lazy regexp compilation to speedup sonic-cfggen
* [sonic-cfggen] address pep8 related comments

Now it's possible to add and remove peers based on ConfigDB
- What I did
Fixed functionality for dynamically adding/removing static bgp peers.
- How I did it
Split the bgp default template on bgp part and bgp peer part
Changed bgpcfgd to use 1.
- How to verify it
Build an image and run on your DUT

If we have a case where have created a fd for i/o and we have removed the
handling thread but still have the fd in the poll data structure, there
existed a case where we would get the handle this fd return from poll but we
would immediately do nothing with it because we didn't have a thread to hand
the event to.
This leads to an infinite loop. Prevent the infinite loop
from happening and log the problem.

lib: changes for making snmp socket non-blocking
Description: The changes have been done to make the snmp socket
non-blocking before calling snmp_read()
FRR Pull request: https://github.com/FRRouting/frr/pull/5134
Problem Description/Summary :
vtysh hangs on first try to enter after a reboot with BGP dynamic peers
Expected Behavior :
VTYSH should not hang.
When we debug more into bgpd docker by doing gdb on its threads, we find the below thread of bgpd, which is causing the issue.

From 5.1 version of PyYAML python module, yaml.load() API is deprecated. Code should be compatible to support both the versions, else error/warning messages are seen like below,

In teamd v1.28, the port can only be enabled if sync bit is set
in recveived LACPDU from partner by the following commit
"teamd: lacp: update port state according to partner's sync bit"
(54f137c105)
However, lacp fallback feature needs to enable port even if partner
LACPDU is not received within a given period and fallback cfg is enabled.
To fix the lacp fallback breakage, we have to bypass the sync bit
check in lacp fallback mode.
