From 7f3b39dafc6234dc1565fafe6adb15a6c4932182 Mon Sep 17 00:00:00 2001 From: Chris Mi Date: Fri, 18 Aug 2017 07:24:20 -0400 Subject: [PATCH] net/sched: Fix the logic error to decide the ingress qdisc The offending commit used a newly added helper function. But the logic is wrong. Without this fix, the affected NICs can't do HW offload. Error -EOPNOTSUPP will be returned directly.
