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