This could be problematic when the work queue item is cancelled via\ncancel_delayed_work_sync() in batadv_v_elp_iface_disable(). In this case,\nan rtnl_lock() would cause a deadlock.\n\nTo avoid this, rtnl_trylock() was used in this function to skip the\nretrieval of the ethtool information in case the RTNL lock was already\nheld.\n\nBut for cfg80211 interfaces, batadv_get_real_netdev() was called - which\nalso uses rtnl_lock().
