Subject: [PATCH v3 net-next] net: make use of helper netif_is_bridge_master()
Make use of netdev helper functions to improve code readability.
Replace 'dev->priv_flags & IFF_EBRIDGE' with netif_is_bridge_master(dev).
Signed-off-by: Kyungrok Chung <acadx0@...il.com>

v1->v2:
- Apply fixes to batman-adv, core too.
v2->v3:
- Fix wrong logic.
