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>
