Eric Dumazet 8df40d1033 sit: enable lockless xmits ... SIT tunnels can benefit from lockless xmits, using NETIF_F_LLTX Bench on a 16 cpus machine (dual E5540 cpus), 16 threads sending 10000000 UDP frames via one sit tunnel (size:220 bytes per frame) Before patch : real 3m15.399s user 0m9.185s sys 51m55.403s 75029.00 87.5% _raw_spin_lock vmlinux 1090.00 1.3% dst_release vmlinux 902.00 1.1% dev_queue_xmit vmlinux 627.00 0.7% sock_wfree vmlinux 613.00 0.7% ip6_push_pending_frames ipv6.ko 505.00 0.6% __ip_route_output_key vmlinux After patch: real 1m1.387s user 0m12.489s sys 15m58.868s 28239.00 23.3% dst_release vmlinux 13570.00 11.2% ip6_push_pending_frames ipv6.ko 13118.00 10.8% ip6_append_data ipv6.ko 7995.00 6.6% __ip_route_output_key vmlinux 7924.00 6.5% sk_dst_check vmlinux 5015.00 4.1% udpv6_sendmsg ipv6.ko 3594.00 3.0% sock_alloc_send_pskb vmlinux 3135.00 2.6% sock_wfree vmlinux 3055.00 2.5% ip6_sk_dst_lookup ipv6.ko 2473.00 2.0% ip_finish_output vmlinux Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
