From e13258f38e927b61cdb5f4ad25309450d3b127d1 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sat, 29 Oct 2016 09:18:43 +0200 Subject: [PATCH] batman-adv: Detect missing primaryif during tp_send as error The throughput meter detects different situations as problems for the current test. It stops the test after these and reports it to userspace. This also has to be done when the primary interface disappeared during the test.
