commit 9e8d507dcb21278d0621fe8290910621d187c5d3 Author: Sven Eckelmann sven@narfation.org Date: Sat Apr 1 14:47:03 2017 +0200

batman-adv: Use ethtool helper to get link status

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.
