+PF and VF Considerations
+The primary goal of DPDK is to provide a Userspace dataplane. Managing VFs from
+a PF driver is a control plane feature and developers should generally rely on
+the Linux Kernel for that.
+The primary goal should be to work with the Linux Kernel community to get the
+required functionality upstream. PF functionality should only be added to DPDK
+for testing and prototyping purposes while the kernel work is ongoing. It should
+also be marked with an "EXPERIMENTAL" tag. If the upstream path is rejected by
+the Linux Kernel community then a case can be made to maintain the PF
+functionality in DPDK without the EXPERIMENTAL tag.

   Support for Mellanox ConnectX-5 family of 10/25/40/50/100 Gbps adapters
   has been added to the existing mlx5 PMD.
+* **Added VF Daemon (VFD) on i40e. - EXPERIMENTAL**
+  This's an EXPERIMENTAL feature to enhance the capability of DPDK PF as many
+  VF management features are not supported by kernel PF driver.
+  Some new private APIs are implemented in PMD without abstrction layer.
+  They can be used directly by some users who have the need.
+  The new APIs to control VFs directly from PF include,
+  1) set VF MAC anti-spoofing
+  2) set VF VLAN anti-spoofing
+  3) set TX loopback
+  4) set VF unicast promiscuous mode
+  5) set VF multicast promiscuous mode
+  6) set VF MTU
+  7) get/reset VF stats
+  8) set VF MAC address
+  9) set VF VLAN stripping
+  10) VF VLAN insertion
+  12) set VF broadcast mode
+  13) set VF VLAN tag
+  14) set VF VLAN filter
+  VFD also includes VF to PF mailbox message management by APP.
+  When PF receives mailbox messages from VF, PF should call the callback
+  provided by APP to know if they're permitted to be processed.
+  As an EXPERIMENTAL feature, please aware it can be changed or even
+  removed without prior notice.
