This patchset adds sctp GSO support. Performance tests indicates that increases throughput by 10% if using bigger chunk sizes, specially if bigger than MTU. For small chunks, it doesn't help much if not using heavy firewall rules. For small chunks it will probably be of more use once we get something like MSG_MORE as David Laight had suggested. v1->v2: Added support for receiving GSO frames on SCTP stack, as requested by Dave Miller. Marcelo Ricardo Leitner (7): loopback: make use of NETIF_F_GSO_SOFTWARE skbuff: export skb_gro_receive sk_buff: allow segmenting based on frag sizes skbuff: introduce skb_gso_validate_mtu sctp: delay as much as possible skb_linearize sctp: Add GSO support sctp: improve debug message to also log curr pkt and new chunk size drivers/net/loopback.c | 5 +- include/linux/netdev_features.h | 7 +- include/linux/netdevice.h | 1 + include/linux/skbuff.h | 8 + include/net/sctp/sctp.h | 4 + include/net/sctp/structs.h | 5 + net/core/ethtool.c | 1 + net/core/skbuff.c | 42 ++++- net/ipv4/af_inet.c | 1 + net/ipv4/ip_forward.c | 2 +- net/ipv4/ip_output.c | 2 +- net/ipv6/ip6_output.c | 2 +- net/mpls/af_mpls.c | 2 +- net/sctp/Makefile | 3 +- net/sctp/input.c | 57 ++++--- net/sctp/inqueue.c | 78 +++++++-- net/sctp/offload.c | 106 ++++++++++++ net/sctp/output.c | 366 +++++++++++++++++++++++++++------------- net/sctp/protocol.c | 3 + net/sctp/socket.c | 2 + 20 files changed, 530 insertions(+), 167 deletions(-) create mode 100644 net/sctp/offload.c -- 2.5.5 -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
