Calculate a score for each 1000 IRQs: - TX completions are worth 1 point - RX completions are worth 4 if merged using LRO or 2 otherwise Reduce moderation if the score is less than 10000, down to a minimum of 5 us. Increase moderation if the score is more than 20000, up to the specified maximum. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
