This patch extends the manpage by providing the description of NEXT-C-SID
support for the SRv6 End.X behavior as defined in RFC 8986 [1].
The code/logic required to handle the "flavors" framework has already been
merged into iproute2 by commit:
04a6b456bf74 ("seg6: add support for flavors in SRv6 End* behaviors").
Some examples:
ip -6 route add 2001:db8::1 encap seg6local action End.X nh6 fc00::1 flavors next-csid dev eth0
Standard Output:
ip -6 route show 2001:db8::1
2001:db8::1 encap seg6local action End.X nh6 fc00::1 flavors next-csid lblen 32 nflen 16 dev eth0 metric 1024 pref medium
JSON Output:
ip -6 -j -p route show 2001:db8::1
