For ixgbe, in order to support VF vlan promiscuous or unicast promiscuous, we need to set PF host register PFVML2FLT of bit UPE and VPE. It also align to ixgbe kernel code version 5.5.3. And also it need to update to the latest API version in order for negotiation between pf and vf, then new API message can be supported.
