From: Sven Eckelmann <s...@narfation.org>
The ethtool_ops of batman-adv never contained more than a stub for the
get_link function pointer. It was always returning that a link exists even
when the devices was not yet up and therefore nothing resampling a link
could have been available.
Instead use the ethtool helper which returns the current carrier state.
