What kind of selftest did you implement? So far I've been doing this: Using a cyclic real time application to create high priority frames and running iperf3 in parallel to simulate low priority traffic constantly. Afterwards, checking the NIC statistics for fragments and so on. Also checking the latency of the RT frames with FPE on/off. BTW, if you guys need help with testing of patches, i do have access to i225 and stmmacs which both support FPE. Also the Hirschmann switches should support it.
