ethtool: Use full 32 bit speed range in ethtool's set_settings
This makes sure the ethtool's set_settings() callback of network drivers don't ignore the 16 most significant bits when ethtool calls their set_settings(). All drivers compiled with make allyesconfig on x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
