selftests: mlxsw: Add ingress RIF configuration test for 802.1D bridge
Before layer 2 forwarding, the device classifies an incoming packet to a FID. After classification, the FID is known, but also all the attributes of the FID, such as the router interface (RIF) via which a packet that needs to be routed will ingress the router block. For VLAN-unaware bridges (802.1D), the FID classification is done according to {Port, VID}. When a RIF is added on top of a FID, all the existing {Port, VID}->FID mappings should be updated by the software with the new RIF. In addition, when a new mapping is added for FID which already has a RIF, the correct RIF should be used for it. Add a test to verify that packets can be routed after {Port, VID}->FID classification, regardless of the order of the configuration. # ./ingress_rif_conf_1d.sh TEST: Add RIF for existing {port, VID}->FID mapping [ OK ] TEST: Add {port, VID}->FID mapping for FID with a RIF [ OK ] Signed-off-by: Amit Cohen <amcohen@nvidia.com> Reviewed-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: Petr Machata <petrm@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
