Hi dpdk dev team,
This is ifen from Advantech.

We have a question about i226 dpdk test result and want to know the i226LM 2.5G dpdk test result.
Intel suggest us to check dpdk.org directly.

But we don’t know who is the right contact window for us asking.. will you please help forward my mail to the right contact windows?

Our result and test config is in following.
we didn’t get our expectation result. [we expected 2.5G x 2 port testing, frameloss shall be 0 at 256B 100% to 1518B 100%]
Do you have your official i226 dpdk test result for us reference? Or maybe you can give us some suggestion about our test config or environment.

Thanks a lot..

b/r,
ifen
