47 | Description: | ||
48 | Writing a device ID to this file will remove an ID | ||
49 | that was dynamically added via the new_id sysfs entry. | ||
50 | The format for the device ID is: | ||
51 | VVVV DDDD SVVV SDDD CCCC MMMM. That is Vendor ID, Device | ||
52 | ID, Subsystem Vendor ID, Subsystem Device ID, Class, | ||
53 | and Class Mask. The Vendor ID and Device ID fields are | ||
54 | required, the rest are optional. After successfully | ||
55 | removing an ID, the driver will no longer support the | ||
56 | device. This is useful to ensure auto probing won't | ||
57 | match the driver to the device. For example: | ||
58 | # echo "8086 10f5" > /sys/bus/pci/drivers/foo/remove_id | ||
