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 include/linux/skbuff.h | 3 ++ net/core/skbuff.c | 85 ++++++++++++++++++++++++++++++++++++ net/netfilter/nfnetlink_queue_core.c | 59 ++----------------------- net/openvswitch/datapath.c | 52 +++++++++++++++++++--- 4 files changed, 137 insertions(+), 62 deletions(-) -- 1.8.3.1
