+* **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.
