The SRv6 End.DT4 is used to implement multi-tenant IPv4 L3VPN. It decapsulates the received packets and performs IPv4 routing lookup in the routing table of the tenant. The SRv6 End.DT4 Linux implementation leverages a VRF device. SRv6 End.DT4 is defined in the SRv6 Network Programming [1]. - Patch 1/4 is needed to solve a pre-existing issue with tunneled packets when a sniffer is attached; - Patch 2/4 introduces two callbacks used for customizing the creation/destruction of a SRv6 behavior; - Patch 3/4 is the core patch that adds support for the SRv6 End.DT4 behavior; - Patch 4/4 adds the selftest for SRv6 End.DT4. I would like to thank David Ahern for his support during the development of this patch set. Comments, suggestions and improvements are very welcome!
