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.
