Change details: - Add debugfs support to obtain firmware trace, saved firmware trace on an IOC crash, driver info and read/write to registers. - debugfs hierarchy: bna/pci_dev:<pci_name> where the pci_name corresponds to the one under /sys/bus/pci/drivers/bna - Following are the new debugfs entries added: fwtrc: collect current firmware trace. fwsave: collect last saved fw trace as a result of firmware crash. regwr: write one word to chip register regrd: read one or more words from chip register. drvinfo: collect the driver information.
