From 33e89097c05cb0bb1816a15aa5ef4740d03eb90a Mon Sep 17 00:00:00 2001 From: Sander Vrijders Date: Fri, 12 Oct 2018 17:17:10 +0200 Subject: ipcpd: Make Qdisc bypass configurable This will make bypassing the qdisc configurable, as it might be handy for getting fast data rates but is generally needed.
