When XDP_USE_NEED_WAKEUP is used and the fill ring is empty so no buffer is allocated on RX side, allow RX NAPI to be descheduled. This avoids wasting CPU cycles on polling. Users will be notified and they need to make a wakeup call after refilling the ring. Signed-off-by: Bui Quang Minh <redacted>Thanks for handling that problem. Please carry my tag in the next version: Reviewed-by: Jason Xing <redacted> You seem to have forgotten to add Xuan Zhuo's tag...
This version contains a bug fix which is a non-trivial change so I think it might not be the same as the version that he approved of. Thanks, Quang Minh.
