The proposed End.DT46 implementation is meant to support the decapsulation of both IPv4 and IPv6 traffic coming from a *single* SRv6 tunnel. The SRv6 End.DT46 Behavior greatly simplifies the setup and operations of SRv6 VPNs in the Linux kernel. - patch 1/2 is the core patch that adds support for the SRv6 End.DT46 Behavior; - patch 2/2 adds the selftest for SRv6 End.DT46 Behavior. The patch introducing the new SRv6 End.DT46 Behavior in iproute2 will follow shortly. Comments, suggestions and improvements are very welcome as always!
