Struct Napi 

pub struct Napi(/* private fields */);

NAPI busy-poll configuration for Submitter::register_napi and Submitter::unregister_napi.

On (un)register the kernel writes the previous settings back into the value, which can be read with busy_poll_timeout and prefer_busy_poll.

Available since Linux 6.9.
