Implement 'devctl clear driver' to undo a previous 'devctl set driver'. 2016-08-29T22:48:36+00:00 John Baldwin jhb@FreeBSD.org 2016-08-29T22:48:36+00:00 e05ec081fe81beb79567b82723bd045aa50f19c0 Add a new 'clear driver' command for devctl along with the accompanying ioctl and devctl_clear_driver() library routine to reset a device to use a wildcard devclass instead of a fixed devclass. This can be used to undo a previous 'set driver' command. After the device's name has been reset to permit wildcard names, it is reprobed so that it can attach to newly-available (to it) device drivers.

Add 'devctl delete' that calls device_delete_child(). 2016-04-27T16:33:17+00:00 John Baldwin jhb@FreeBSD.org 2016-04-27T16:33:17+00:00 88eb5c506d00e446dcfeb0f84b36d5132a8d9f6b 'devctl delete' can be used to delete a device that is no longer present. As an anti-foot-shooting measure, 'delete' will not delete a device unless it's parent bus says it is no longer present. This can be overridden by passing the force ('-f') flag. Note that this command should be used with care. If a device is deleted that is actually present it can't be resurrected unless the parent bus device's driver supports rescans.
