From 1f15bb4f399ceccd85522b24af31198f53516f9b Mon Sep 17 00:00:00 2001 From: Vlad Buslov Date: Tue, 12 Feb 2019 23:39:06 +0200 Subject: net: sched: flower: only return error from hw offload if skip_sw Recently introduced tc_setup_flow_action() can fail when parsing tcf_exts on some unsupported action commands. However, this should not affect the case when user did not explicitly request hw offload by setting skip_sw flag. Modify tc_setup_flow_action() callers to only propagate the error if skip_sw flag is set for filter that is being offloaded, and set extack error message in that case.
