#### 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
- 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.
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 in each namespace (sonic interfaces and linux interface) is 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 .

Update topology script to retrieve hwsku from minigraph
if hwsku information is not available in config_db.
Fix clean up of interfaces in msft_multi_asic_vs hwsku
topology script.
- Why I did it
When bringing up multi-asic VS switch, topology service is started during boot up.
Topology service starts a shell script which runs the topology script present in /usr/share/sonic/device// directory. To invoke hwsku specific script, the topology script tries to retrieve hwsku information from config_db.
During initial boot up config_db might not be populated. In order to start topology service before config_db is updated,
update topology script to get hwsku information from minigraph.xml if it is available.
This will be helpful to bring up multi-asic VS testbed by loading minigraph and starting topology service.
- How I did it
Update topology.sh script to retrieve hwsku information from minigraph.xml.
Fix clean up function on msft_multi_asic_vs toplogy script.
- How to verify it
single-asic VS - no change; topology service is only enabled for multi-asic VS.
multi-asic VS - Bring up multi-asic VS image, copy minigraph to vs image, start topology service. Topology service should be successful.
to test clean up function fix, start topology service - make sure interfaces are created and moved to the right namespaces.
stop topology service - make sure namespace do not have any interface and all front end interfaces are present in default namespace.
#### Why I did it
Add new SKU for SN2700 Mellanox system that supports the following port configuration:
8 X 100G
40 X 50G
8 X 10G
#### How I did it
Add new Folder - "Mellanox-SN2700-D40C8S8" under /sonic-buildimage/device/mellanox/x86_64-mlnx_msn2700-r0/
that contains the relevant files supporting this SKU
#### How to verify it
Bring up the image, run "show interface status" and make sure that all ports are up and reflect the following requirement:
Port 1/3 will be used as 4x10G
Port 2/4 - Not exist (blocked since 1 and 3 split to 4)
Port 7/8/9/10/23/24/25/26 will used as 100G
All other ports will be used as 2x50G

#### Description for the changelog
Support new SKU under the name of SN2700-D40C8S8
**- Why I did it**
- The thermalctld daemon on the Pmon docker requires support from the thermal manager API.
**- How I did it**
- Removed the old function for detecting a faulty fan.
- Removed the old function for detecting excess temperature.
- Implement thermal_manager APIs based on ThermalManagerBase
- Implement thermal_conditions APIs based on ThermalPolicyConditionBase
- Implement thermal_actions APIs based on ThermalPolicyActionBase
- Implement thermal_info APIs based on ThermalPolicyInfoBase
- Add thermal_policy.json
**- Why I did it**
There is a preference to use thermalctld instead of fancontrol for 201911 release branch. The Arista platform submodule updates and thermal policies in the platforms will allow Arista devices to use thermalctld instead of fancontrol.
**- How I did it**
I cherry-picked the necessary commits from master branch for sonic-platform-modules-arista into 201911 branch. I've also added the file to skip fancontrol and added the thermal policies json.
**- How to verify it**
On Gardena, Upperlake, Clearlake, and Lodoga thermalctld is up and running with no errors. Fans show ~29%.

**- Why I did it**
Converted two SP model to single pool model and modified the buffer size.
**- How I did it**
Changed buffer_default settings for all the DellEMC Z9264f HWSKU's.
**- How to verify it**
Check SP register values in NPU shell.
**- Which release branch to backport (provide reason below if selected)**
Need to be cherry picked for 201911 branch.
Treat devices that are ToRRouters (ToRRouters and BackEndToRRouters) the same when rendering templates
Except for BackEndToRRouters belonging to a storage cluster, since these devices have extra sub-interfaces created

Refactor SFP reset, low power get/set API, and plugins with new SDK SX APIs. Previously they were calling SDK SXD APIs which have glibc dependency because of shared memory usage.
Remove implementation "set_power_override", "tx_disable_channel", "tx_disable" which using SXD APIs, once related SDK SX API available, will add them back based on new SDK SX APIs.
**- Why I did it**
There is error i2c mapping for port 11,12 and port 19, 20.
**- How I did it**
Fix to correct i2c mapping

As part of consolidating all common Python-based functionality into the new sonic-py-common package, this pull request:
1. Redirects all Python applications/scripts in sonic-buildimage repo which previously imported sonic_device_util or sonic_daemon_base to instead import sonic-py-common, which was added to the 201911 branch in https://github.com/Azure/sonic-buildimage/pull/5063
2. Replaces all calls to `sonic_device_util.get_platform_info()` to instead call `sonic_py_common.get_platform()` and removes any calls to `sonic_device_util.get_machine_info()` which are no longer necessary (i.e., those which were only used to pass the results to `sonic_device_util.get_platform_info()`.
3. Removes unused imports to the now-deprecated sonic-daemon-base package and sonic_device_util.py module
This is a step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999
