2022-02-09ice: Support configuring the device to Double VLAN ModeBrett Creeley1-0/+1
In order to support configuring the device in Double VLAN Mode (DVM), the DDP and FW have to support DVM. If both support DVM, the PF that downloads the package needs to update the default recipes, set the VLAN mode, and update boost TCAM entries. To support updating the default recipes in DVM, add support for updating an existing switch recipe's lkup_idx and mask. This is done by first calling the get recipe AQ (0x0292) with the desired recipe ID. Then, if that is successful update one of the lookup indices (lkup_idx) and its associated mask if the mask is valid otherwise the already existing mask will be used. The VLAN mode of the device has to be configured while the global configuration lock is held while downloading the DDP, specifically after the DDP has been downloaded. If supported, the device will default to DVM.

2022-02-09ice: Add outer_vlan_ops and VSI specific VLAN ops implementationsBrett Creeley1-0/+37
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.
