[dpdk-dev] [PATCH v3 07/13] net/mvpp2: detach Tx QoS from Rx cls/QoS config

[Andrzej Ostruszka <amo@semihalf.com>]

From: Yuval Caduri <cyuval@marvell.com>

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'.
