SubjectCONFIG_TULIP_NAPI_HW_MITIGATION latency question.
"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:

low levels traffic at the cost of a small latency.
x
x If in doubt, say Y.
