Subject: [PATCH ipsec-next v2 0/7] xfrm: remove three more indirect calls from packet path

v2: rebase on top of ipsec-next, no other changes.

This patch series removes three more indirect calls from the state_afinfo
struct.

These are:
- extract_input (no dependencies on other modules)
- output_finish (same)
- extract_output (has dependency on ipv6 module, but
  that is only needed for pmtu detection, so the indirect
  call cost is not required for each packet).

Functions get moved to net/xfrm and the indirections are removed.
pmtu detection will be handled via ipv6_stubs.

Florian Westphal (7):
      xfrm: avoid extract_output indirection for ipv4
      xfrm: state: remove extract_input indirection from xfrm_state_afinfo
      xfrm: move xfrm4_extract_header to common helper
      xfrm: expose local_rxpmtu via ipv6_stubs
      xfrm: place xfrm6_local_dontfrag in xfrm.h
      xfrm: remove extract_output indirection from xfrm_state_afinfo
      xfrm: remove output_finish indirection from xfrm_state_afinfo
