Bug 213669 uncovered regression in PMTU discovery for UDP-encapsulated
routes and some incorrect usage in udp tunnel fields. This series fixes
problems and also adds such case for selftests

v2:
 - remove refactor code that was in first patch
 - move checking logic to __udp{4,6}_lib_err_encap
 - add more tests, especially routed configuration

Vadim Fedorenko (2):
  udp: check encap socket in __udp_lib_err_encap
  selftests: net: add ESP-in-UDP PMTU test
