Respin of the zerocopy patches for the openvswitch upcall.
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
