[PATCH net-next 0/9] selftests: pmtu: Add further vti/vti6 MTU and PMTU tests

Patches 4/9 to 9/9 add tests to verify default MTU assignment for
vti4 and vti6 interfaces, to check that MTU values set on new
link and link changes are properly taken and validated, and to
verify PMTU exceptions on vti4 interfaces.

Patch 1/9 fixes the helper to fetch exceptions MTU to run in the
passed namespace.

Patches 2/9 and 3/9 are preparation work to make it easier to
introduce those tests.

  selftests: pmtu: Use namespace command prefix to fetch route mtu
  selftests: pmtu: Factor out MTU parsing helper
  selftests: pmtu: Introduce support for multiple tests
