      [IPv4/IPv6]: UFO Scatter-gather approach · e89e9cf5
      Ananda Raju 提交于
      Attached is kernel patch for UDP Fragmentation Offload (UFO) feature.
      
      1. This patch incorporate the review comments by Jeff Garzik.
      2. Renamed USO as UFO (UDP Fragmentation Offload)
      3. udp sendfile support with UFO
      
      This patches uses scatter-gather feature of skb to generate large UDP
      datagram. Below is a "how-to" on changes required in network device
      driver to use the UFO interface.
      
      UDP Fragmentation Offload (UFO) Interface:
      -------------------------------------------
      UFO is a feature wherein the Linux kernel network stack will offload the
      IP fragmentation functionality of large UDP datagram to hardware. This
      will reduce the overhead of stack in fragmenting the large UDP datagram to
      MTU sized packets
      
      1) Drivers indicate their capability of UFO using
      dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG
      
      NETIF_F_HW_CSUM is required for UFO over ipv6.
      
      2) UFO packet will be submitted for transmission using driver xmit routine.
      UFO packet will have a non-zero value for
      
      "skb_shinfo(skb)->ufo_size"
      
      skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP
      fragment going out of the adapter after IP fragmentation by hardware.
      
      skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[]
      contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW
      indicating that hardware has to do checksum calculation. Hardware should
      compute the UDP checksum of complete datagram and also ip header checksum of
      each fragmented IP packet.
      
      For IPV6 the UFO provides the fragment identification-id in
      skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating
      IPv6 fragments.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
