Hi @qiluo-msft , we intend to remove the whole if block because:
- if platform is not mellanox, it will trigger graceful shutdown flow no matter what type it is. It means that removing the condition won't affect any other vendor.
- if platform is mellanox, it will trigger graceful shutdown if type is not cold (old logic). This is exactly what we try to fix. We move the
type != coldcheck to Syncd.cpp, see PR Ignore removing switch for mellanox platform due to known limitation sonic-sairedis#1216 .

@Junchao-Mellanox IMO this fix is not relevant any more and the sairedis changes were reverted. |

Depends on sonic-net/sonic-sairedis#1216
Why I did this?
Due to a limitation in mellanox platform, sonic ignores syncs graceful shutdown in syncd.sh previously. However, ignoring graceful shutdown in syncd.sh also ignores closing other resources such as removing all counters.
This PR changes syncd shutdown flow for mellanox platform to make sure it execute graceful shutdown flow. There is another PR for sonic-sairedis to make sure mellanox platform does not call remove_switch for cold shutdown.
How I test this?
Running config reload on many platforms and check result.
