Why I did it
Arista 7060 platform has a rare and unreproduceable PCIe timeout that could possibly be solved with increasing the switch PCIe timeout value. To do this we'll call a script for this platform to increase the PCIe timeout on boot-up.
No issues would be expected from the setpci command. From the PCIe spec:
"Software is permitted to change the value in this field at any
time. For Requests already pending when the Completion
Timeout Value is changed, hardware is permitted to use either
the new or the old value for the outstanding Requests, and is
permitted to base the start time for each Request either on when
this value was changed or on when each request was issued. "
How I did it
Add "platform-init" support in swss docker similar to how "hwsku-init" is called, only this would be for any device belonging to a platform. Then the script would reside in device data folder.
Additionally, add pciutils dependency to docker-orchagent so it can run the setpci commands.
How to verify it
On bootup of an Arista 7060, can execute:
lspci -vv -s 01:00.0 | grep -i "devctl2"
In order to check that the timeout has changed.
- Use SfpOptoeBase by default to leverage new `sonic_xcvr` refactor
- Add support for `Woodleaf` product
- Move `libsfp-eeprom.so` to a different `.deb` package
- Add new logrotate configuration for arista logs
- Improve logging mechanism for the drivers (IO loglevel, fix syslog duplicates)
- Initialize chassis cards in parallel
- Refactor of `get_change_event` to fix interrupts treated as presence change
#### Why I did it
Add platform_asic file to each platform folder in sonic-device-data package. The file content will be used as the ground truth of mapping from PLATFORM_STRING to switch ASIC family.
One use case of the mapping is to prevent installing a wrong image, which targets for other ASIC platforms. For example, currently we have several ONIE images naming as sonic-*.bin, it's easy to mistakenly install the wrong image. With this mapping built into image, we could fetch the ONIE platform string, and figure out which ASIC it is using, and check we are installing the correct image.
After this PR merged, each platform vendor has to add one mandatory text file `device/PLATFORM_VENDOR/PLATFORM_STRING/platform_asic`, with the content of the platform's switch ASIC family.
I will update https://github.com/Azure/SONiC/wiki/Porting-Guide after this PR is merged.
You can get a list of the ASIC platforms by `ls -b platform | cat`. Currently the options are
```
barefoot
broadcom
cavium
centec
centec-arm64
generic
innovium
marvell
marvell-arm64
marvell-armhf
mellanox
nephos

Also support

#### How I did it
#### How to verify it
Test one image on DUT. And check the folders under `/usr/share/sonic/device`
Depends on Azure/sonic-utilities#1626
Depends on Azure/sonic-swss#1754
QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.
Example:
Config DB:
"Ethernet92|3": {
"scheduler": "[SCHEDULER|scheduler.1]",
"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"
},
"Ethernet0|0": {
"profile": "[BUFFER_PROFILE|ingress_lossy_profile]"
},
"Ethernet0": {
"dscp_to_tc_map": "[DSCP_TO_TC_MAP|AZURE]",
"pfc_enable": "3,4",
"pfc_to_queue_map": "[MAP_PFC_PRIORITY_TO_QUEUE|AZURE]",
"tc_to_pg_map": "[TC_TO_PRIORITY_GROUP_MAP|AZURE]",
"tc_to_queue_map": "[TC_TO_QUEUE_MAP|AZURE]"
},
This format is not consistent with other DB schema followed in sonic.
And also this reference in DB is not required, This is taken care by YANG "leafref".
Removed this format from all platform files to consistent with other sonic db schema.
Example:
"Ethernet92|3": {
"scheduler": "scheduler.1",
"wred_profile": "AZURE_LOSSLESS"
},

Why I did it
Fix an issue on the Clearwater2 linecard.
When the linecard is started with a fresh image without configuration, phys would not be initialized.
How I did it
Added default_sku for Clearwater2 which prevents config-setup from failing to create a default config_db.json.
Added some extra logic in the phy-credo-init script to run the phy_config.sh of the hwsku pointed by default_sku if the DEVICE_METADATA.localhost.hwsku information is not populated in CONFIG_DB.
How to verify it
Booting an image with this change and without configuration will lead to the phys being initialized using the phy_config.sh from default_sku.
- Disable health monitoring of `psu.voltage` until support is implemented
- chassis: disable provisioning bit once linecard has booted
- chassis: fix issue in `show version` when running as `admin`
- chassis: fix race when reading an eeprom before it's available
- chassis: implement `get_all_asics` call
- api: fix `ChassisBase.get_system_eeprom_info` implementation
- api: add missing thermal condition and info
- api: fix return value of `ChassisBase.set_status_led`
- sfp: introduce SfpOptoeBase implementation used based on configuration knob
- psu: rely on pmbus to read input/output status when other mechanism is missing
- misc: other refactors and improvements

Why I did it
To support dynamic port breakout Broadcom configurations on Arista platforms.
How I did it
Updated platform.json for platforms and added new hwsku, Broadcom config, and hwsku.json for dynamic port breakout usage.
The name of the new hwsku name used is very similar to the platform name (platform x86_64-arista_7050_qx32s hwsku Arista-7050QX-32S) as the flex hwsku is meant to be the default in the future.
How to verify it
Boot up device with the new hwsku, interfaces are up.
Change hwsku.json with new default breakout mode and reload device, breakout will have successfully been applied.

This change introduces dynamic port breakout (DPB) for Arista 7050 QX32 model by adding a new SKU suffixed with `-Flex`.
The breakout configuration allowed is the same as in mainline Arista EOS, i.e. 24 first ports are allowed to be used in 4x10G in addition to the default 40G mode. The last 8 ports are fixed to 40G. This is due to ASIC limitations of a total of 104 max ports.
**NOTE**: As described in https://github.com/aristanetworks/sonic/issues/30#issuecomment-820584113 front panel LEDs are likely not working when operating in breakout mode. It is not clear if the LEDs work correctly in 40G mode as I have not had a chance to physically inspect the switch with this patch.

Dynamic Port Breakout fall in case "autoneg" field exist in config_db.
