commit dfb5f80c9db1b535524a2baec80bbfa6c69791e3 Author: Antonio Quartulli ordex@autistici.org Date: Tue Oct 16 10:04:39 2012 +0200

batman-adv: support array of debugfs general attributes

This patch adds support for an array of debugfs general (not soft_iface specific) attributes. With this change it will be possible to add more general attributes by simply appending them to the array without touching the rest of the code.
