Hi Daniel,

Good catch :)
We plan to deliver a fix for that bug in coming DPDK release.
It is very similar to yours one, though we need extra check that there are no VFs enabled for that port.

The fix looks good. Thanks.

Please, could you add a detailed explanation and a signed-off as described in the guidelines:

I think it's a good idea to point to the commit which has introduced the bug.
Note also that "RSS rx" may be simply "RSS".

Thank you
