"at the cost of a small latency"

How much additional latency is added with this option enabled?

5ms? 10ms?

-> Use Interrupt Mitigation
x CONFIG_TULIP_NAPI_HW_MITIGATION:
x Use HW to reduce RX interrupts. Not strict necessary since NAPI reduces RX interrupts but itself. Although this reduces RX interrupts even at low levels traffic at the cost of a small latency. x
x If in doubt, say Y. x
