[SCSI] lpfc 8.1.2: Misc FC Discovery changes :
Misc FC Discovery changes : - Added FC_BYPASSED_MODE statistic - Corrected some log message data - Fix up Discovery infrastructure to support FAN: Allow Fabric entities to flow thru DSM Fix up linkup/linkdown unregister login processing for Fabric entities Clean up Discovery code Utilize nodev_tmo for Fabric entities - Use of 3 * ratov for CT handling timeouts - Fix up DSM to make more appropriate decisions and clean up code.
