* 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
Added python-libpcap to be used by arp_responder.py utility. This is needed to set conf.use_pcap which will make sure that L2pcapListenSocket uses libpcap instead of Linux PF_PACKET sockets. By using libpcap the vlan field will not be removed when the application receives the packet.
Implement Watchdog platform2.0 API for DellEMC S6100 platform.
- Added new file watchdog.py in sonic_platform directory.
- Enabled API support to Enable/disable watchdog.
Implement part of the Chassis and Fan related APIs.
- Chassis APIs
get_base_mac()
get_serial_number()
get_serial_number()
get_system_eeprom_info()
get_reboot_cause()
- Fan APIs
get_direction()
get_speed()
get_target_speed()
get_speed_tolerance()
set_speed()
set_status_led()
get_target_speed()
- Fan APIs base on Device API
get_name()
get_presence()
get_model()
get_serial()
get_status()

Fixed the fpga crash issue which we see in 15-20 mins time frame after onie-install. Accessing stale i2c transfer message buffer causes this crash. Te message buffer becomes stale due to race between i2c transfer and fpga interrupt handler.
This new state STATE_STOP will not be exposed for the wake up call till all the ISR of previous transfer is completed successfully.
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

We noticed in tests/production that there is a low probability failure
where /etc/hosts could have some garbage characters before the entry for
local host name. The consequence is that all sudo command would be very
slow. In extreme cases it would prevent some services from starting
properly.
I suspect that the /etc/hosts file might be opened by some process causing
the issue. Editing contents with new file level and replace the whole file
should be safer.
