commit 454b849c7de18a7b44eecebe889f5f3149d24780 Author: Antonio Quartulli antonio@open-mesh.com Date: Fri Apr 19 18:07:01 2013 +0200
batman-adv: print the VID properly
Since the MSB bits of any vid variable are now used for storing flags, print the vid properly by taking the flags away and printing -1 in case of VID representing no real VLAN.
