    Fix the checksum feature advertised in device flags.  The hardware support
    TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers).
    However, the kernel feature flags do not distinguish IPv6 with/without
    extension headers.
    
    Therefore, the driver needs to use NETIF_F_IP_CSUM instead of
    NETIF_F_HW_CSUM since the latter includes all IPv6 packets.
    
    A future patch can be created to check for extension headers and perform
    software checksum calculation.
