> The current implementation of IPv6 SR supports SRH insertion/encapsulation

> a packet whose active segment (IPv6 DA) is routed to the local node). This
> behavior simply consists of updating the DA to the next segment and forwarding
> the packet accordingly. This processing is realised for all such packets,
> regardless of the active segment.

> The most recent specifications of IPv6 SR [1] [2] extend the SRH processing
> features as follows. Each segment endpoint defines a MyLocalSID table.
> This table maps segments to operations to perform. For each ingress IPv6
> packet whose DA is part of a given prefix, the segment endpoint looks
> up the active segment (i.e., the IPv6 DA) in the MyLocalSID table and
> applies the corresponding operation. Such specifications enable to specify
> arbitrary operations besides the basic SRH processing and allow for a more
> fine-grained classification.

> This patch series implements those extended specifications by leveraging
> a new type of lightweight tunnel, seg6local.

Series applied, thanks David.
