[PATCH net-next 0/2] net: ipv6: seg6: extack messages for lwtunnel setup

[Gabriel Goller]

seg6_build_state() rejects invalid lwtunnel configurations with a bare -EINVAL,
so "ip route add ... encap seg6 ..." always reports "Invalid argument".

Patch 1 attaches an extack message to each of them.

Patch 2 adds a ksft/ynl selftest that hits some rejection paths and checks the
error messages.

Gabriel Goller (2):
  net: ipv6: seg6: report lwtunnel setup errors via extack
  selftests: seg6: check extack messages on SRv6 lwtunnel setup
