#### Why I did it
SAI profile files speed configuration have wrong bitmap value for 10/50G speed option.
#### How I did it
Fix to the correct value for all SPC1 devices.
#### How to verify it
Configure on these platforms ports with 10/50G speed using this fix.

#### Why I did it
To enable parsing the `AutoNegotiation` element from the LinkMetadata section of minigraph file
#### How I did it
Parse the value `AutoNegotiation` element from the `LinkMetadata` section of minigraph file. If the element is present, an `autoneg` key will be added to the port in the `PORT` table of Config DB with a value of either `0` or `1`
If an `autoneg` value is present in port_config.ini, the value from the minigraph will take precedence, overriding that value.
Also remove `AutoNegotiation` and `EnableAutoNegotiation` elements from the `DeviceInfo` section, as we will use this data in the `LinkMetadata` section to determine whether to enable auto-negotiation for a port.
Why I did it
It was observed that on a multi-asic DUT bootup, the BGP internal sessions between ASIC's was taking more time to get ESTABLISHED than external BGP sessions. The internal sessions was coming up almost exactly 120 secs later.
In multi-asic platform the bgp dockers ( which is per ASIC ) on switch start are bring brought up around the same time and they try to make the bgp sessions with neighbors (in peer ASIC's) which may be not be completely up. This results in BGP connect fail and the retry happens after 120sec which is the default Connect Retry Timer
How I did it
Add the command to set the bgp neighboring session retry timer to 10sec for internal bgp neighbors.

Why I did it
To monitor the SSD health condition in DellEMC S6100 platform post upgrade.
A daemon is introduced to monitor the SSD every one hour.
To check for SSD status at boot time and at the time of cold-reboot.
All these changes are supported only for newer SSD firmware.
Added a platform_reboot_pre_check script to prevent cold-reboot based on SSD status.
Depends on Azure/sonic-utilities#1472

Closes issue #6982.
The issue was root caused as we were using the unix_socket for reading from DB as a default mechanism (#5250). The redis unix socket is created as follows.
admin@str--acs-1:~$ ls -lrt /var/run/redis/redis.sock
srwxrw---- 1 root redis 0 Mar 6 01:57 /var/run/redis/redis.sock
So it used to work fine for the user "root" or if user is part of redis group ( admin was made part of redis group by default )
Check if the user is with sudo permissions then use the redis unix socket, else fallback to tcp socket.
This PR is cherry-pick of master
https://github.com/Azure/sonic-buildimage/pull/6920
Why I did it
Add support for BGP Monitors on multi asic SONiC platforms.
How I did it
On multi ASIC SONiC platforms, BGP monitor session will be established from Backend ASIC.
To achieve this following changes are done
Add BGP monitor configuration on the backend ASIC.
The BGP monitor configuration is present in the DPG of the device in minigraph.xml of multi-ASIC device, so this configuration will be added to the config_db of the host, when the minigraph is loaded.
To add configuration for this in the Backend ASIC, a new class MultiAsicBgpMonCfg is added to the hostcfgd service to update the config_db of the backend ASIC when the BGP_MONITOR table of the host config_db is updated.
This way incremental BGP_MONITOR configuration can also be handled.
Changes to establish BGP session with bgp monitor.
Add route in host main routing table to go to one of pre-define backend asic
Add IP table rule on front asic to mark the BGP packets with destination as IPv4 Loopback.
Add IP rule in front asic namespace to match mark BGP packet and lookup default table
Program the default route in FrontEnd asic name space docker default table as part of start.sh of the BGP container.
It need to be done as part of start.sh otherwise FRR default route will get over-written.

#### Why I did it
Change buffer config for new SKU Mellanox-SN2700-D40C8S8
#### How I did it
Reuse the buffer config of SKU Mellanox-SN2700-D48C8
#### How to verify it
Run sonic-mgmt qos test and all passed
This is to address the issue when "mmuconfig -p egress_lossy_profile" is executed which causes SYNCd failure with SAI_STATUS_INSUFFICIENT_RESOURCE for attr SAI_BUFFER_PROFILE_ATTR_RESERVED_BUFFER_SIZE.
This change also requires the change from (https://github.com/Azure/sonic-swss/pull/1649)
This SAI change was already tested as part of the (https://github.com/Azure/sonic-swss/pull/1649) PR.
1. Made the command next-hop-self force only applicable on back-end asic bgp. This is done so that BGPL iBGP session running on backend can send e-BGP learn nexthop. Back end asic FRR is able to recursively resolve the eBGP nexthop in its routing table since it knows about all the connected routes advertise from front end asic.
2. Made all front-end asic bgp use global loopback ip (Loopback0) as router id and back end asic bgp use Loopbacl4096 as ruter-id and originator id for Route-Reflector. This is done so that routes learnt by external peer do not see Loopback4096 as router id in show ip bgp <route-prerfix> output.
3. To handle above change need to pass Loopback4096 from BGP manager for jinja2 template generation. This was missing and this change/fix is needed for this also https://github.com/Azure/sonic-buildimage/blob/master/dockers/docker-fpm-frr/frr/bgpd/templates/dynamic/instance.conf.j2#L27
4. Enhancement to add mult_asic specific bgpd template generation unit test cases.
Enable BBR config allowas-in 1 for internal peers
Why I did:

Fix Issue #6537
- Why I did it
Current mutli-asic vs hwsku consists of 6 asics with each asic having 32 interfaces. When bringing this up, below issue was seen:
When all 32 interfaces(sonic interfaces and linux interface) are set to 9100 mtu, DMA error is seen "DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:06:03.0" which can be fixed by updating swiotlb=65536 in /host/grub/grub.cfg .In order to keep multi-asic VS lighter and easier to bring up and test, new hwsku 'msft_four_asic_vs' is added to represent 4-asic hwsku with 2 frontend asics and 2 backend asics and each asic having 8 interfaces interconnected by port-channels.
- How I did it
Add msft_four_asic_hwsku directory to have the right number of directories (4) and update port_config.ini and lanemap.ini files to include 8 ports information.
Add topology.sh script to create the internal asic-asic connectivity.
- How to verify it
Update asic.conf with the 4 asic information as below and build sonic-vs.img:
NUM_ASIC=4
DEV_ID_ASIC_0=0
DEV_ID_ASIC_1=1
DEV_ID_ASIC_2=2
DEV_ID_ASIC_3=3
Modify sonic_multiasic.xml to have 8 front panel interfaces.
create virtual switch using "sudo virsh sonic_mutliasic.xml" command.
Start topology service and Load config_db files for switch and each asic.
Ensure that that all internal interfaces and port_channels are coming up.
multi-asic vs testbed:
Bring up mutli-asic VS testbed with a multi-asic image(asic.conf updated to 4 asics) and using t1-lag topology.
./testbed-cli.sh -t vtestbed.csv -m veos_vtb -k ceos add-topo vms-kvm-four-asic-t1-lag password.txt
Load minigraph/config_dbs.
Ensure all internal and external interfaces come up.
No change on single asic vs.
