From f39872d966aa39c0ae767002828d09ddba44ccd1 Mon Sep 17 00:00:00 2001 From: Rui Salvaterra Date: Sun, 19 Dec 2021 19:29:58 +0000 Subject: [PATCH] kernel: generic: select the fq_codel qdisc by default The kernel configuration allows us to select a default qdisc. Let's do this for 5.10 (as 5.4 is on its way out) and get rid of the hacky patch we've been carrying.
