[NET]: IPV6 checksum offloading in network devices
The existing model for checksum offload does not correctly handle devices that can offload IPV4 and IPV6 only. The NETIF_F_HW_CSUM flag implies device can do any arbitrary protocol. This patch: * adds NETIF_F_IPV6_CSUM for those devices * fixes bnx2 and tg3 devices that need it * add NETIF_F_IPV6_CSUM to ipv6 output (incl GSO) * fixes assumptions about NETIF_F_ALL_CSUM in nat * adjusts bridge union of checksumming computation Signed-off-by: David S. Miller <davem@davemloft.net>
