Subject: [B.A.T.M.A.N.] [PATCH v5 16/19] batman-adv: Add orig_interval mesh genl configuration
Date: Sat, 9 Feb 2019 14:41:06 +0100 [thread overview]
Message-ID: <20190209134109.14908-17-sven@narfation.org> (raw)
In-Reply-To: <20190209134109.14908-1-sven@narfation.org>
The OGM packets are transmitted every orig_interval milliseconds. This
value can be changed using the configuration interface.
The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the
configuration of this feature using the u32 BATADV_ATTR_ORIG_INTERVAL
attribute.
