Subject: [PATCH ipsec-next 0/3] xfrm: add offload support for esp beet mode

This patchset is to add gso_segment functions for esp4 and esp6
beet mode, and prep function for both, and tested with 6 cases:

  1. IPv4 INNER ADDRESSES
     - OUTER v4 ADDRESSES
     - OUTER v6 ADDRESSES

  2. IPv4 INNER ADDRESSES with options
     - OUTER v4 ADDRESSES
     - OUTER v6 ADDRESSES

  3. IPv6 INNER ADDRESSES
     - OUTER v4 ADDRESSES
     - OUTER v6 ADDRESSES

With this patchset, an esp beet mode skb would be segmented and
encryped until it arrives in dev_queue_xmit()/validate_xmit_skb().

Xin Long (3):
  esp4: add gso_segment for esp4 beet mode
  esp6: add gso_segment for esp6 beet mode
  xfrm: add prep for esp beet mode offload
