    [NET]: IPV6 checksum offloading in network devices · d212f87b
    Stephen Hemminger 提交于
    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
