Subject: scsi: qla2xxx: edif: Use link event to wake up app
Patch-mainline: v5.16-rc1
Git-commit: 527d46e0b0147f2b32b78ba49c6a231835b24a41
References: bsc#1190941

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.
