[JOSHI, KAUSTUBH (KAUSTUBH)]

John,

Thanks for comments. To answer a specific question you raised:

In our case, the answer is yes. We intend to use the PF through DPDK to house a high speed packet mirror function for capturing packet traces from VFs (for ops etc). 

However, in theory, this *can* be done through an extra VF as well, so I didn't bring up that particular point as being a deciding factor in this debate.
