2023-07-24ice: implement bridge port vlanMichal Swiatkowski1-0/+8
Port VLAN in this case means push and pop VLAN action on specific vid. There are a few limitation in hardware: - push and pop can't be used separately - if port VLAN is used there can't be any trunk VLANs, because pop action is done on all traffic received by VSI in port VLAN mode - port VLAN mode on uplink port isn't supported Reflect these limitations in code using dev_info to inform the user about unsupported configuration. In bridge mode there is a need to configure port vlan without resetting VFs. To do that implement ice_port_vlan_on/off() functions. They are only configuring correct vlan_ops to allow setting port vlan. We also need to clear port vlan without resetting the VF which is not supported right now. Change it by implementing clear_port_vlan ops. As previous VLAN configuration isn't always the same, store current config while creating port vlan and restore it in clear function. Configuration steps: - configure switchdev with bridge - #bridge vlan add dev eth0 vid 120 pvid untagged - #bridge vlan add dev eth1 vid 120 pvid untagged - ping from VF0 to VF1 Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Signed-off-by: Wojciech Drewek <wojciech.drewek@intel.com> Tested-by: Sujai Buvaneswaran <sujai.buvaneswaran@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
2022-02-09ice: Add outer_vlan_ops and VSI specific VLAN ops implementationsBrett Creeley1-0/+6
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: Use the proto argument for VLAN opsBrett Creeley1-2/+2
Currently the proto argument is unused. This is because the driver only supports 802.1Q VLAN filtering. This policy is enforced via netdev features that the driver sets up when configuring the netdev, so the proto argument won't ever be anything other than 802.1Q. However, this will allow for future iterations of the driver to seemlessly support 802.1ad filtering. Begin using the proto argument and extend the related structures to support its use.

2022-02-09ice: Introduce ice_vlan structBrett Creeley1-5/+4
Add a new struct for VLAN related information. Currently this holds VLAN ID and priority values, but will be expanded to hold TPID value. This reduces the changes necessary if any other values are added in future. Remove the action argument from these calls as it's always ICE_FWD_VSI.

2022-02-09ice: Add new VSI VLAN opsBrett Creeley1-0/+27
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.
