We're not sure if we want to change and maintain a totally new DPDK PF either. 
So, we only change PMD code and not expose it to abstraction layer. It can only be used by some users who have the needs. 
It's experimental and comes from the users' requirement. If it's good enough and accepted by other NICs, we can expose it. 
If it's not good, it still can be a choice before Linux kernel provides.
