====================
selftests: forwarding: Add tests for VXLAN routing
VXLAN routing allows hosts in different overlay networks (i.e.,
different VNIs) to communicate with one another.
Two popular routing models are asymmetric and symmetric routing.
In asymmetric routing the ingress VTEP routes the packet into the
correct VXLAN tunnel, whereas the egress VTEP only bridges the packet to
the correct host. Therefore, packets in different directions use
different VNIs - the target VNI.
In symmetric routing both the ingress and egress VTEPs perform routing
in the overlay network into / from the VXLAN tunnel. Packets in
different directions use the same VNI - the L3 VNI. Different tenants
(VRFs) use different L3 VNIs.
Patch #1 adds a test for asymmetric routing. Patches #2-#3 reuse the
topology and add test cases for ARP decapsulation and suppression.
Patch #4 adds a test for symmetric routing.
