# [*content_string*]
|
|
# (required) String which shall be written to the script file.

# [*udev_rules*]
|
|
# (required) String of lines to write to udev rules to ensure
|
|
# VFs are reconfigured if the PCI devices are removed and
|
|
# readded without rebooting (e.g. when physical functions were
|
|
# allocated to VMs)
