Make the code align to VLAN v1, like:

	/* Vlan stripping setting v2 */
	if (vf->vf_res->vf_cap_flags & VIRTCHNL_VF_OFFLOAD_VLAN_V2) {
		if (dev_conf->rxmode.offloads & DEV_RX_OFFLOAD_VLAN_STRIP)
			iavf_enable_vlan_strip_v2(ad);
		else
			iavf_disable_vlan_strip_v2(ad);
	}

	/* Vlan stripping setting */
	if (vf->vf_res->vf_cap_flags & VIRTCHNL_VF_OFFLOAD_VLAN) {
		if (dev_conf->rxmode.offloads & DEV_RX_OFFLOAD_VLAN_STRIP)
			iavf_enable_vlan_strip(ad);
		else
			iavf_disable_vlan_strip(ad);
	}
