* origin/topic/jsiwek/mobile-ipv6:
  Add support for mobile IPv6 Mobility Header (RFC 6275).
  Refactor IP_Hdr routing header handling, add MobileIPv6 Home Address handling.
  Revert TCP checksumming to cache common data, like it did before.
  Revert "Improve handling of IPv6 Routing Type 0 headers."
  Improve handling of IPv6 routing type 0 extension headers.
