This is the callback function for FLOGI failure roundrobin FCF failover read FCF record mailbox command from the eligible FCF record bmask for performing the failover. If the FCF read back is not valid/available, it fails through to retrying FLOGI to the currently registered FCF again. Otherwise, if the FCF read back is valid and available, it will set the newly read FCF record to the failover FCF record, unregister currently registered FCF record, copy the failover FCF record to the current FCF record, and then register the current FCF record before proceeding to trying FLOGI on the new failover FCF.

This function iterates through all the fcf records available in HBA and chooses the optimal FCF record for discovery. After finding the FCF for discovery it registers the FCF record and kicks start discovery. If FCF_IN_USE flag is set in currently used FCF, the routine tries to use an FCF record which matches fabric name and mac address of the currently used FCF record. If the driver supports only one FCF, it will try to use the FCF record used by BOOT_BIOS.
