2022-02-09ice: Add outer_vlan_ops and VSI specific VLAN ops implementationsBrett Creeley1-12/+95
Add a new outer_vlan_ops member to the ice_vsi structure as outer VLAN ops are only available when the device is in Double VLAN Mode (DVM). Depending on the VSI type, the requirements for what operations to use/allow differ. By default all VSI's have unsupported inner and outer VSI VLAN ops. This implementation was chosen to prevent unexpected crashes due to null pointer dereferences. Instead, if a VSI calls an unsupported op, it will just return -EOPNOTSUPP. Add implementations to support modifying outer VLAN fields for VSI context. This includes the ability to modify VLAN stripping, insertion, and the port VLAN based on the outer VLAN handling fields of the VSI context. These functions should only ever be used if DVM is enabled because that means the firmware supports the outer VLAN fields in the VSI context. If the device is in DVM, then always use the outer_vlan_ops, else use the vlan_ops since the device is in Single VLAN Mode (SVM). Also, move adding the untagged VLAN 0 filter from ice_vsi_setup() to ice_vsi_vlan_setup() as the latter function is specific to the PF and all other VSI types that need an untagged VLAN 0 filter already do this in their specific flows. Without this change, Flow Director is failing to initialize because it does not implement any VSI VLAN ops.

2022-02-09ice: Adjust naming for inner VLAN operationsBrett Creeley1-5/+5
Current operations act on inner VLAN fields. To support double VLAN, outer VLAN operations and functions will be implemented. Add the "inner" naming to existing VLAN operations to distinguish them from the upcoming outer values and functions. Some spacing adjustments are made to align values. Note that the inner is not talking about a tunneled VLAN, but the second VLAN in the packet. For SVM the driver uses inner or single VLAN filtering and offloads and in Double VLAN Mode the driver uses the inner filtering and offloads for SR-IOV VFs in port VLANs in order to support offloading the guest VLAN while a port VLAN is configured.

2022-02-09ice: Add new VSI VLAN opsBrett Creeley1-0/+20
Incoming changes to support 802.1Q and/or 802.1ad VLAN filtering and offloads require more flexibility when configuring VLANs. The VSI VLAN interface will allow flexibility for configuring VLANs for all VSI types. Add new files to separate the VSI VLAN ops and move functions to make the code more organized.
