3 Contact: Stephen Hemminger <sthemmin@microsoft.com>
5 This file allows the driver for a device to be specified which
6 will override standard static and dynamic ID matching. When
7 specified, only a driver with a name matching the value written
8 to driver_override will have an opportunity to bind to the
9 device. The override is specified by writing a string to the
10 driver_override file (echo uio_hv_generic > driver_override) and
11 may be cleared with an empty string (echo > driver_override).
12 This returns the device to standard matching rules binding.
13 Writing to driver_override does not automatically unbind the
14 device from its current driver or make any attempt to
15 automatically load the specified driver. If no driver with a
16 matching name is currently loaded in the kernel, the device
17 will not bind to any driver. This also allows devices to
18 opt-out of driver binding using a driver_override name such as
19 "none". Only a single driver may be specified in the override,
20 there is no support for parsing delimiters.
