[ovs-dev] [PATCH 0/2 v4] Open vSwitch zerocopy upcall

[Thomas Graf]

Respin of the zerocopy patches for the openvswitch upcall.

V4: - Daniel Borkmann pointed out that the style in skbuff.h has changed
      in net-next, adapted to no longer using extern in headers.
V3: - Removed unneeded alignment of nlmsg_len after padding 
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() for upcall
