> In ixgbe_get_settings() the link status and speed of the interface are determined
> based on a read from the LINKS register via the call to mac.ops.check.link(). This
> can cause issues where external drivers may end up with unknown speed when
> calling ethtool_get_setings().
> 
> Instead of calling the mac.ops.check_link() we can report the speed from the
> adapter structure which is populated by the driver.
