This is pending on the discussion at stephenxs/SONiC#12, with regard to making this a generic feature, if possible. |

@Junchao-Mellanox now that it is not single value how the user is expected to understand the errors? should we add some information in the CLI? we cannot assume users has the code :-) Please confirm which HLD we should refer in this PR. Is it sonic-net/SONiC#586 ? |
1. Update get_change_event
- Return event in a bitmap format in case there is an error
- Return an extra map indexed by sfp_error in case there is a Mellanox-specific error
- Indicate whether the error is a blocking error
2. Expose the error status of SFP modules to CLI
- A platform API calls SDK API to fetch the error status
- Display the SFP module state: plugged, unplugged and plugged with error.
- The SFP error state is displayed only if the SFP module state is plugged with error
- The CLI will call platform API and provide user-friendly output
3. Redirect stderr to /dev/null in order to eliminate errors in case SFP module is not plugged
4. Beautify the code, making all the state/error/descriptions defined in a uniform place
