  "message": "[IPV6]: Added GSO support for TCPv6\n\nThis patch adds GSO support for IPv6 and TCPv6.  This is based on a patch\nby Ananda Raju \u003cAnanda.Raju@neterion.com\u003e.  His original description is:\n\n\tThis patch enables TSO over IPv6. Currently Linux network stacks\n\trestricts TSO over IPv6 by clearing of the NETIF_F_TSO bit from\n\t\"dev-\u003efeatures\". This patch will remove this restriction.\n\n\tThis patch will introduce a new flag NETIF_F_TSO6 which will be used\n\tto check whether device supports TSO over IPv6. If device support TSO\n\tover IPv6 then we don\u0027t clear of NETIF_F_TSO and which will make the\n\tTCP layer to create TSO packets. Any device supporting TSO over IPv6\n\twill set NETIF_F_TSO6 flag in \"dev-\u003efeatures\" along with NETIF_F_TSO.\n\n\tIn case when user disables TSO using ethtool, NETIF_F_TSO will get\n\tcleared from \"dev-\u003efeatures\". So even if we have NETIF_F_TSO6 we don\u0027t\n\tget TSO packets created by TCP layer.\n\n\tSKB_GSO_TCPV4 renamed to SKB_GSO_TCP to make it generic GSO packet.\n\tSKB_GSO_UDPV4 renamed to SKB_GSO_UDP as UFO is not a IPv4 feature.\n\tUFO is supported over IPv6 also\n\n\tThe following table shows there is significant improvement in\n\tthroughput with normal frames and CPU usage for both normal and jumbo.\n\n\t--------------------------------------------------\n\t|          |     1500        |      9600         |\n\t|          ------------------|-------------------|\n\t|          | thru     CPU    |  thru     CPU     |\n\t--------------------------------------------------\n\t| TSO OFF  | 2.00   5.5% id  |  5.66   20.0% id  |\n\t--------------------------------------------------\n\t| TSO ON   | 2.63   78.0 id  |  5.67   39.0% id  |\n\t--------------------------------------------------\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S.
