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