Aaron, since we don't care about DPDK or the Mellanox PMD in this use case, the warning message seems harmless... but do you know any way that we can suppress it at run time?

Comment 2 Aaron Conole 2018-06-01 21:31:03 UTC

I don't know currently how it can be suppressed.  Perhaps the -37 version will pull in the correct rdma core dependencies so it won't be an issue.  Please retest when the newest version drops.

Comment 5 Ben Bennett 2019-11-15 16:57:33 UTC

This is really something that needs to be fixed upstream in OVN and is completely harmless anyway.  It's just log noise that confuses people.
