[NET]: Add ethtool support for NETIF_F_IPV6_CSUM devices.
Add ethtool utility function to set or clear IPV6_CSUM feature flag. Modify tg3.c and bnx2.c to use this function when doing ethtool -K to change tx checksum. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
