From 406aeb15240179e6faf53b22917252ec2b17695b Mon Sep 17 00:00:00 2001 From: Yuval Caduri Date: Tue, 25 Sep 2018 09:05:03 +0200 Subject: [PATCH] net/mvpp2: detach Tx QoS from Rx cls/QoS config Functional change: Open receive cls/qos related features, only if the config file contains an rx_related configuration entry. This allows to configure tx_related entries, w/o unintentionally opening rx cls/qos. Code: 'use_global_defaults' is by default set to '1'. Only if an rx_related entry was configured, it is updated to '0'. rx cls/qos is performed only if 'use_global_defaults' is '0'. Default TC configuration is now only mandatory when 'use_global_defaults' is '0'.
