Subject: [PATCH 0/3] xfrm: ESP Traffic Flow Confidentiality padding (v3)

The following patchset adds Traffic Flow Confidentiality padding. The
first patch introduces a new Netlink XFRM attribute to configure TFC via
userspace. Patch two and three implement the padding logic in IPv4 and
IPv6 ESP. Padding is always done using the RFC4303 format an is clamped
to the PMTU.

Changes from v2:
  - Remove unused flag field in attribute, use a plain u32 as attribute payload
  - Reject installation of TFC padding on non-tunnel SAs
