What: /sys/bus/pci/drivers/qla2xxx/.../devices/*
Date: September 2009
Contact: QLogic Linux Driver <linux-driver@qlogic.com>
Description: qla2xxx-udev.sh currently looks for uevent CHANGE events to
signal a firmware-dump has been generated by the driver and is
ready for retrieval.
Users: qla2xxx-udev.sh. Proposed changes should be mailed to
linux-driver@qlogic.com
