From af20b710479ae662829cf739b521390daa7fcbcb Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sun, 17 Apr 2011 20:39:07 +0200 Subject: [PATCH] batman-adv: Set the txqueuelen to zero when creating soft interface MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Like other virtual interfaces, e.g. br0, we don't need a transmit queue. Packets should only be queued on real interfaces which are underneath. In practice this patch makes little difference since the virtual interfaces can accept packets as fast as they come, but the patch will avoid bufferbloat questions to the mailling lists in the future.
