HC2VPP-288 - add SRv6 module (writers only)
Changes: - add new module for SRv6 - add models for SRv6 configuration: from https://datatracker.ietf.org/doc/draft-raza-spring-srv6-yang/ - hc2vpp-ietf-srv6-base@2018-03-01.yang - hc2vpp-ietf-srv6-static@2018-03-01.yang - ietf-srv6-types@2018-03-01.yang - implements Configuration of local sids and their end functions. - implements support for FIB table management (HC2VPP-345) Models hc2vpp-ietf-srv6-base and hc2vpp-ietf-srv6-static are changed (HC2VPP-332): - imports for routing models (HC2VPP-298) - presence in end function containers was added to fix mandatory child verification if parent container is not present Change-Id: Ib74e48023b671383f076b84773e26ce7c5ae282a Signed-off-by: Michal Cmarada <michal.cmarada@pantheon.tech> Signed-off-by: Jan Srnicek <jan.srnicek@pantheon.tech>

+
+== Implemented features:
+
+- locator read,write and delete requests and customizers,
+ based on augmentation of routing model in: +
+ `hc2vpp-ietf-routing:routing/hc2vpp-ietf-srv6-base:srv6/locators/locator`
+- local sid read,write and delete requests and customizers,
+ based on augmentation of routing model in: +
+ `hc2vpp-ietf-routing:routing/hc2vpp-ietf-srv6-base:srv6/locators/locator/static/local-sids/sid/`
+- encapsulation source write and delete requests and customizers,
+ based on augmentation of routing model in: +
+ `hc2vpp-ietf-routing:routing/hc2vpp-ietf-srv6-base:srv6/hc2vpp-ietf-srv6-base:encapsulation`
+
+== VPP mapping
+
+- local sid and locator configuration maps to *sr_localsid_add_del* in VPP API:
+ *IPv6 SR LocalSID add/del params:* +
+ *is_del* Boolean of whether its a delete instruction +
+ *localsid_addr* IPv6 address of the localsid +
+ *end_psp* Boolean of whether decapsulation is allowed in this function +
+ *behavior* Type of behavior (function) for this localsid +
+ *sw_if_index* Only for L2/L3 xconnect. OIF. In VRF variant the fib_table. +
+ *vlan_index* Only for L2 xconnect. Outgoing VLAN tag. +
+ *fib_table* FIB table in which we should install the localsid entry +
+ *nh_addr6* Next Hop IPv6 address. Only for L2/L3 xconnect. +
+ *nh_addr4* Next Hop IPv6 address. Only for L2/L3 xconnect. +
+- encapsulation source maps to *sr_set_encap_source* in VPP API: +
+ *IPv6 SR Set SRv6 encapsulation source params:* +
+ *bsid* is the bindingSID of the SR Policy +
+ *index* is the index of the SR policy
+
+
+== Supported End function configurations:
+
+- *END* (VPP behavior type 1)
+- *END X* (VPP behavior type 2)
+- *END DX2* (VPP behavior type 5)
+- *END DX4* (VPP behavior type 7)
+- *END DX6* (VPP behavior type 6)
+- *END T* (VPP behavior type 3)
+- *END DT4* (VPP behavior type 9)
+- *END DT6* (VPP behavior type 8)
