2019-01-20Merge branch 'mlxsw-spectrum_router-Add-GRE-tunnel-support-for-Spectrum-2'David S. Miller14-30/+954
Ido Schimmel says: ==================== mlxsw: spectrum_router: Add GRE tunnel support for Spectrum-2 Nir says: In Spectrum-2, HW implementation of layer 3 tunnels differs from Spectrum-1 when it comes to the underlay routing table selection. Spectrum-2 uses a dedicated RIF that points to the virtual router used for forwarding the encapsulated packets, while Spectrum-1 explicitly specifies the virtual router itself. Patches #1 and #2 add additional fields in RITR - Router interface table register and RTDP - Routing tunnel decap properties respectively, the fields are required for the new underlay RIF needed for Spectrum-2. Patches #3-4 allow different set of RIF operations per ASIC type. The first patch splits the operations and the following patch sets RIF ops according to ASIC type. Patches #5-9 introduce small changes to existing code to allow existence of a dedicated underlay RIF along with the underlay virtual router, and to support that new type of RIF that has no device. Patch #10 takes care of updating the tunnel decap properties egress underlay RIF required for Spectrum-2. Patch #11 adds the implementation of Spectrum-2 specific RIF operations and essentially enables layer 3 GRE tunnels on Spectrum-2. Finally patches #12-18 add tests for GRE IP-in-IP tunnels, both in flat and hierarchical topologies. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Spectrum-2 underlay RIF is merely an auxiliary RIF that points to the virtual router used for encapsulated packets lookup. It exists only when its overlay RIF exists but may be shared with other overlay RIFs. Hence it is undesired to mark any device as related to it. Therefore allow usage of NULL device when allocating RIF.
