| Description: This entry is used by a Unisys support script installed on the |
| guest, and triggered by a udev event. The support script is |
| responsible for enabling and disabling SR-IOV devices when the |
| PF device is being recovered in another guest. |
| |
| Some SR-IOV devices have problems when the PF is reset without |
| first disabling all VFs attached to that PF. s-Par handles this |
| situation by sending a message to guests using these VFs, and |
| the script will disable the device. When the PF is recovered, |
| another message is sent to the guests to re-enable the VFs. |
| |
| The parahotplug/deviceenabled interface is used to acknowledge |
| the recovery message. |
