Subject: [PATCH 08/14] batman-adv: add debugfs support to view multiif tables
Date: Mon, 13 Jan 2014 23:31:32 +0100 [thread overview]
Message-ID: <1389652298-472-9-git-send-email-antonio@meshcoding.com> (raw)
In-Reply-To: <1389652298-472-1-git-send-email-antonio@meshcoding.com>
From: Simon Wunderlich <simon@open-mesh.com>
Show tables for the multi interface operation. Originator tables
are added per hard interface.
This patch also changes the API by adding the interface to the
bat_orig_print() parameters.
