Message

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

Vadim Fedorenko (3):
  udp: check for encap using encap_enable
  udp: check encap socket in __udp_lib_err
  selftests: net: add ESP-in-UDP PMTU test
