|
* Usage is simple, allocate a new id to the stub driver and bind the
|
||
|
* device to it. For example:
|
||
|
*
|
||
|
* # echo "8086 10f5" > /sys/bus/pci/drivers/pci-stub/new_id
|
||
|
* # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/e1000e/unbind
|
||
|
* # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/pci-stub/bind
|
||
|
* # ls -l /sys/bus/pci/devices/0000:00:19.0/driver
|
||
|
* .../0000:00:19.0/driver -> ../../../bus/pci/drivers/pci-stub
