This patch adds a new sysfs attribute to the network device class.
Said attribute provides a per-device control to enable/disable the
threaded mode for all the napi instances of the given network device.
User sets it to 1 or 0 to enable or disable threaded mode per device.
However, when user reads from this sysfs entry, it could return:
  1: means all napi instances belonging to this device have threaded
mode enabled.
  0: means all napi instances belonging to this device have threaded
mode disabled.
  -1: means the system fails to enable threaded mode for certain napi
instances when user requests to enable threaded mode. This happens
when the kthread fails to be created for certain napi instances.

Can you document the new threaded sysfs attribute under
Documentation/ABI/testing/sysfs-class-net?

OK. Will do.
