Hi, I've reviewed this patchset - few comments/questions on it... 

I haven't tested yet - but I'm wondering what is the impact to the dpdk -c 
parameter. Is it no longer used for OVS? 

At present the NON_PMD_CORE_ID define overrides the db settings (which is 
clearly documented). Is it needed now that a db key is available? Perhaps 
it would make things simpler that the define is overridden when a key is 
specified?
