- Why I did it
Add new breakout modes to be used in PAM4 supported cables
- How I did it
- How to verify it
Verified the 50G per lane breakout modes are applied properly on the switch

- Why I did it
The capability files were incorrect in comparison to the marketing spec of the SN4410 platform.
- How I did it
Aligned the capability files according to the marketing spec.
- How to verify it
Basic manual sanity checks:
1. Check if critical docker containers were UP
2. Check if interfaces were created and were UP
3. Check if interfaces created in the syncd docker container by executing – sx_api_ports_dump.py script
4. Check the logs from the start of the switch – everything was OK
5. Verified the port breakout

- Why I did it
The MSN4410 platform was missing 2x100G and 4x50G supported breakout modes in platform.json
- How I did it
Added the aforementioned breakout modes to platform.json
- How to verify it
Run show interface breakout on a MSN4410 and verify that 2x100G and 4x50G are listed in the supported breakout modes for ports 1-24.
- Why I did it
The default breakout mode according to hwsku.json for the MSN4410 is 1x400G and this is not a supported breakout mode according to its platform.json
This causes a conflict on boot of this platform and no containers on the switch will init successfully.
- How I did it
Referenced the platform specification files and updated platform.json
- How to verify it
Install master version of SONiC on MSN4410
Boot switch and verify swss is successfully running using docker ps
#### Why I did it
Current platform.json lacks some peripheral device related facts, like chassis/fan/pasu/drawer/thermal/components names, numbers, etc.
#### How I did it
Add platform device facts to the platform.json file

To fix [DPB| wrong aliases for interfaces](https://github.com/Azure/sonic-buildimage/issues/6024) issue, implimented flexible alias support [design doc](https://github.com/Azure/SONiC/pull/749)
> [[dpb|config] Fix the validation logic of breakout mode](https://github.com/Azure/sonic-utilities/pull/1440) depends on this
#### How I did it
1. Removed `"alias_at_lanes"` from port-configuration file(i.e. platfrom.json)
2. Added dictionary to "breakout_modes" values. This defines the breakout modes available on the platform for this parent port, and it maps to the alias list. The alias list presents the alias names for individual ports in order under this breakout mode.
```
{
"interfaces": {
"Ethernet0": {
"index": "1,1,1,1",
"lanes": "0,1,2,3",
"breakout_modes": {
"1x100G[40G]": ["Eth1"],
"2x50G": ["Eth1/1", "Eth1/2"],
"4x25G[10G]": ["Eth1/1", "Eth1/2", "Eth1/3", "Eth1/4"],
"2x25G(2)+1x50G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"],
"1x50G(2)+2x25G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"]
}
}
}
```
#### How to verify it
`config interface breakout`

- Why I did it
platform.json and hwsku.json files are required for a feature called Dynamic Port Breakout
- How I did it
Created capability files according to platform specification SN4410
- How to verify it
Full qualification requires bugs fixes reported under sonic-buildimage
