pasemi_mac: Improve RX interrupt mitigation
pasemi_mac: Improve RX interrupt mitigation Currently the receive side interrupts will go off on the reception of a packet, NAPI will poll the ring and keep polling as long as there's a decent amount of packets to receive. This is less than optimal, especially for LRO where it's better if we have a more substantial amount of packets to process at once, to get the real LRO benefits. So, set the count threshold to a higher value and use the timeout feature that will give us an interrupt even if not enough packets have come in to set off the count threshold. FIXME: It'd be real nice to have ethtool support for users to tune this at runtime. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
