+ *
+ * For example, if the PF populates the virtchnl_vlan_caps.offloads in the
+ * following manner the VF will be allowed to enable and/or disable 0x8100 inner
+ * VLAN insertion and/or stripping via the opcodes listed above. Inner in this
+ * case means the outer most or single VLAN from the VF's perspective. This is
+ * because no outer offloads are supported. See the comments above the
+ * virtchnl_vlan_supported_caps structure for more details.
+ *
+ * virtchnl_vlan_caps.offloads.stripping_support.inner =
+ * VIRTCHNL_VLAN_TOGGLE |
+ * VIRTCHNL_VLAN_ETHERTYPE_8100;
+ *
+ * virtchnl_vlan_caps.offloads.insertion_support.inner =
+ * VIRTCHNL_VLAN_TOGGLE |
+ * VIRTCHNL_VLAN_ETHERTYPE_8100;
+ *
+ * In order to enable inner (again note that in this case inner is the outer
+ * most or single VLAN from the VF's perspective) VLAN stripping for 0x8100
+ * VLANs, the VF would populate the virtchnl_vlan_setting structure in the
+ * following manner and send the VIRTCHNL_OP_ENABLE_VLAN_STRIPPING_V2 message.
+ *
+ * virtchnl_vlan_setting.inner_ethertype_setting =
+ * VIRTCHNL_VLAN_ETHERTYPE_8100;
+ *
+ * virtchnl_vlan_setting.vport_id = vport_id or vsi_id assigned to the VF on
+ * initialization.
+ *
+ * The reason that VLAN TPID(s) are not being used for the
+ * outer_ethertype_setting and inner_ethertype_setting fields is because it's
+ * possible a device could support VLAN insertion and/or stripping offload on
+ * multiple ethertypes concurrently, so this method allows a VF to request
+ * multiple ethertypes in one message using the virtchnl_vlan_support
+ * enumeration.
+ *
+ * For example, if the PF populates the virtchnl_vlan_caps.offloads in the
+ * following manner the VF will be allowed to enable 0x8100 and 0x88a8 outer
+ * VLAN insertion and stripping simultaneously. The
+ * virtchnl_vlan_caps.offloads.ethertype_match field will also have to be
+ * populated based on what the PF can support.
+ *
+ * virtchnl_vlan_caps.offloads.stripping_support.outer =
+ * VIRTCHNL_VLAN_TOGGLE |
+ * VIRTCHNL_VLAN_ETHERTYPE_8100 |

+ * virtchnl_vlan_caps.offloads.insertion_support.outer =
+ * VIRTCHNL_VLAN_TOGGLE |
+ * VIRTCHNL_VLAN_ETHERTYPE_8100 |
+ * VIRTCHNL_VLAN_ETHERTYPE_88A8 |
+ * VIRTCHNL_VLAN_ETHERTYPE_AND;
+ *
+ * In order to enable outer VLAN stripping for 0x8100 and 0x88a8 VLANs, the VF
+ * would populate the virthcnl_vlan_offload_structure in the following manner
+ * and send the VIRTCHNL_OP_ENABLE_VLAN_STRIPPING_V2 message.
+ *
+ * virtchnl_vlan_setting.outer_ethertype_setting =
+ * VIRTHCNL_VLAN_ETHERTYPE_8100 |
+ * VIRTHCNL_VLAN_ETHERTYPE_88A8;
+ *
+ * virtchnl_vlan_setting.vport_id = vport_id or vsi_id assigned to the VF on
+ * initialization.
+ *
+ * There is also the case where a PF and the underlying hardware can support
+ * VLAN offloads on multiple ethertypes, but not concurrently. For example, if
+ * the PF populates the virtchnl_vlan_caps.offloads in the following manner the
+ * VF will be allowed to enable and/or disable 0x8100 XOR 0x88a8 outer VLAN
+ * offloads. The ethertypes must match for stripping and insertion.
+ *
+ * virtchnl_vlan_caps.offloads.stripping_support.outer =
+ * VIRTCHNL_VLAN_TOGGLE |
+ * VIRTCHNL_VLAN_ETHERTYPE_8100 |
+ * VIRTCHNL_VLAN_ETHERTYPE_88A8 |
+ * VIRTCHNL_VLAN_ETHERTYPE_XOR;
+ *
+ * virtchnl_vlan_caps.offloads.insertion_support.outer =

+ * VIRTCHNL_VLAN_ETHERTYPE_8100 |
+ * VIRTCHNL_VLAN_ETHERTYPE_88A8 |
+ * VIRTCHNL_VLAN_ETHERTYPE_XOR;
+ *
+ * virtchnl_vlan_caps.offloads.ethertype_match =
+ * VIRTCHNL_ETHERTYPE_STRIPPING_MATCHES_INSERTION;
+ *
+ * In order to enable outer VLAN stripping for 0x88a8 VLANs, the VF would
+ * populate the virtchnl_vlan_setting structure in the following manner and send
+ * the VIRTCHNL_OP_ENABLE_VLAN_STRIPPING_V2. Also, this will change the
+ * ethertype for VLAN insertion if it's enabled. So, for completeness, a
+ * VIRTCHNL_OP_ENABLE_VLAN_INSERTION_V2 with the same ethertype should be sent.
+ *
+ * virtchnl_vlan_setting.outer_ethertype_setting = VIRTHCNL_VLAN_ETHERTYPE_88A8;

+ * VIRTCHNL_OP_DISABLE_VLAN_FILTERING_V2
+ *
+ * VF sends this message to enable or disable VLAN filtering. It also needs to
+ * specify an ethertype. The VF knows which VLAN ethertypes are allowed and
+ * whether or not it's allowed to enable/disable filtering via the
+ * VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS message. The VF needs to
+ * parse the virtchnl_vlan_caps.filtering fields to determine which, if any,
+ * filtering messages are allowed.
+ *
+ * For example, if the PF populates the virtchnl_vlan_caps.filtering in the
+ * following manner the VF will be allowed to enable/disable 0x8100 and 0x88a8
+ * outer VLAN filtering together. Note, that the VIRTCHNL_VLAN_ETHERTYPE_AND
+ * means that all filtering ethertypes will to be enabled and disabled together
+ * regardless of the request from the VF. This means that the underlying
+ * hardware only supports VLAN filtering for all VLAN the specified ethertypes
+ * or none of them.

+ * In order to enable outer VLAN filtering for 0x88a8 and 0x8100 VLANs (0x9100
