[ipsec-next,0/5] xfrm: ipv6: remove hdr_off indirection

Message

IPV6 xfrm moves mutable extension headers to make space for the
encapsulation header.

For Mobile ipv6 sake this uses an indirect call (ipv6 can be built
as module).

These patches remove those indirections by placing a
small parsing function in the xfrm core.

While at it, the merged dstopt/rt hdroff function is
realigned with ip6_find_1stfragopt (where they were copied from).

ip6_find_1stfragopt received bug fixes that were missing from the
cloned ones.

Florian Westphal (5):
  xfrm: ipv6: add xfrm6_hdr_offset helper
  xfrm: ipv6: move mip6_destopt_offset into xfrm core
  xfrm: ipv6: move mip6_rthdr_offset into xfrm core
  xfrm: remove hdr_offset indirection
  xfrm: merge dstopt and routing hdroff functions
