When the driver handles multiple packets per NAPI poll, it is better to reload the receive ring, then tell the hardware. Otherwise, under packet storm with flow control, the driver/hardware will degrade down to one packet getting through per pause-exchange. Likewise on transmit, don't wakeup until a little more than minimum ring space is available. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
