Because as Zhao Wei explained in v1 thread, in ixgbe_vlan_offload_config ,
ETH_VLAN_FILTER_MASK and DEV_RX_OFFLOAD_VLAN_EXTEND are ignored
This looks like VLAN_FILTER AND VLAN_EXTEND offload is not supported and I
didn't see you reply for that, so I assume you agree with that.

OK, seems vlan filter is able to be configured for ixgbevf, but I don't know
how this will work because vlan filter table needs to be enabled first
(ixgbe_vlan_hw_filter_enable)
So at least when it work with a DPDK PF, vlan filter will not work, maybe
kernel PF driver will enable it by default? Could you share more insight?
And same question to VLAN_EXTEND
