This patch extends the manpage by providing a brief description of the PSP flavor for the SRv6 End 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").
