| * 1) When Commissioner pairs with CHIP device, store device nodeId in Fabric table as NodeId |
| * and store commissioner nodeId in Fabric table as FabricId (This is temporary until AddOptCert is implemented and |
| * Fabrics are implemented correctely) 2) When pairing is complete, commissioner calls SetFabric to set the vendorId on the newly |
| * created fabric. The corresponding fabric is found by looking in fabric table and finding a fabric that has the matching |
| * commissioner node ID as fabricId + device nodeId as nodeId and an uninitialized vendorId. 3) RemoveFabric uses the passed in |
| * fabricId, nodeId, vendorID to find matching entry and remove it from fabric table. Once fabricIndex is implemented, it |
