unmodified_drivers: enable unplug per default
|
|
|
|
Since xen-3.3 an official unplug protocol for emulated hardware is
|
|
available in the toolstack. The pvops kernel does the unplug per
|
|
default, so it is safe to do it also in the drivers for forward ported
|
|
xenlinux.
|
|
Currently its required to load xen-platform-pci with the module
|
|
parameter dev_unplug=all, which is cumbersome.
|
|
Also recognize the dev_unplug=never parameter, which provides the
|
|
default before this patch.
