Re: Setting up DPDK PMD Test Suite

Hi Andrew,

I have a couple questions about needed setup of the NICs for the ethdev
test suite.

Our MCX5s and XL710s are failing the checkup tests. The pass rate appears
to be much worse on the XL710s (40 of 73 tests failed, 3 passed
unexpectedly).

For the XL710s, I've updated the driver and NVM versions to match the
minimum supported versions in the compatibility matrix found on the DPDK
documentation. This did not change the failure rate much.
For the MCX5s, I've installed the latest LTS version of the OFED bifurcated
driver on the DUT. Is it needed on the tester?

Are there any other manual setup steps for these devices that I might be
missing?

Thanks,
Adam
