Respin of the zerocopy patches for the openvswitch upcall.

V2: - Added skb_zerocopy_headlen() to calculate headroom of destination
      buffer. This also takes care of the from->head_frag issue.
    - Attribute alignment for frag_list case
    - API documentation
    - performance data for CHECKSUM_PARTIAL tx case

Thomas Graf (2):
  net: Export skb_zerocopy() to zerocopy from one skb to another
  openvswitch: Use skb_zerocopy() to prepare skb for upcall
