[ Upstream commit 527d46e0b0147f2b32b78ba49c6a231835b24a41 ]
Authentication application may be running and in the past tried to probe driver (app_start) but was unsuccessful. This could be due to the bsg layer not being ready to service the request. On a successful link up, driver will use the netlink Link Up event to notify the app to retry the app_start call.
In another case, app does not poll for new NPIV host. This link up event would notify app of the presence of a new SCSI host.
