# SFF compliant transceiver initialization
1. Add new flag 'skip_non_cmis_mgr' and platform/hwsku to set this appropriately indicating whether it's supporting determinstic link bring-up sequence (per this document) or not. Default to be set to true for SFF (i.e. non-CMIS) compliant transeivers
2. xcvrd to do the following as part of its main thread (for initialization/boot-up/restart scenarios)
- Spawn a new worker thread SFFManagerTask() to handle SFF (aka non-CMIS) transceivers (optical modules)
