      [SCSI] qla2xxx: Add Fibre Channel Event (FCE) tracing support. · df613b96

      FCE support enables the firmware to record FC extended link
      services and basic link services frames which have been
      transmitted and received by the ISP.  This allows for a limited
      view of the FC traffic through the ISP without using a FC
      analyzer.  This can be useful in situations where a physical
      connection to the FC bus is not possible.
      
      The driver exports this information in two ways -- first, via a
      debugfs node exported for all supported ISPs under:
      
      	<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce
      
      where a read of the 'fce' file will provide a snapshot of the
      firmware's FCE buffer; and finally, the FCE buffer will be
      extracted during a firmware-dump scenario.
