NETIF_F_HW_CSUM is a superset of NETIF_F_IP_CSUM+NETIF_F_IPV6_CSUM, but
some drivers miss the difference. Fix this and also fix UFO dependency
on checksumming offload as it makes the same mistake in assumptions.

There were no curly braces in this if condition so it always enabled full
duplex.

And ecmd->speed is an unsigned short so it is never equal to -1.  The
effect is that mii_ethtool_sset() fails with -EINVAL and an error is
printed to dmesg.
