Subject: [PATCH 5/7] cxgb4: Add support for T4 hardwired driver configuration settings
In case if user defined configuration file at /lib/firmware/cxgb4/t4-config.txt
location and also factory default configuration file written to FLASH are not
present then driver will use hardwired configuration settings.
