For example, if the PR is requested for master, 202211 and 202012, then the requester needs to provide test results on master and 202012. --> Run warm-reboot, fast-reboot multiple times and verify no errors in the log. #### Which release branch to backport (provide reason below if selected) <!-- - Note we only backport fixes to a release branch, *not* features! - Please also provide a reason for the backporting below. - e.g. - [x] 202006 --> - [ ] 201811 - [ ] 201911 - [ ] 202006 - [ ] 202012 - [ ] 202106 - [ ] 202111 - [x] 202205 - [x] 202311 - [x] 202405 #### Tested branch (Please provide the tested image version) <!-- - Please provide tested image version - e.g. - [x] 20201231.100 --> - [ ] <!-- image version 1 --> - [ ] <!-- image version 2 --> #### Description for the changelog <!-- Write a short (one line) summary that describes the changes in this pull request for inclusion in the changelog: --> <!-- Ensure to add label/tag for the feature raised. example - PR#2174 under sonic-utilities repo. where, Generic Config and Update feature has been labelled as GCU. --> #### Link to config_db schema for YANG module changes <!-- Provide a link to config_db schema for the table for which YANG model is defined Link should point to correct section on https://github.com/Azure/sonic-buildimage/blob/master/src/sonic-yang-models/doc/Configuration.md --> #### A picture of a cute animal (not mandatory but encouraged)
