From: Paolo Abeni <pabeni@redhat.com> this patch adds a new sysfs attribute to the network device class. Said attribute is a bitmask that allows controlling the threaded mode for all the napi instances of the given network device. The threaded mode can be switched only if related network device is down.

Hi, Could someone describe the bitmask (is it a bit per instance of the network device?). And how to use the sysfs interface, please?
