From 619502f7178fef30e726ba57b5a49b61c1c1a276 Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Fri, 19 Oct 2018 11:38:54 +0200 Subject: tools: Specify QoS cube for data transfer flows The ipcp connect command can now set a specific qos cube for data transfer flows. For management flows, the tool ignores this and defaults to raw until data flows are stable enough.
