2017-12-12gianfar: Disable EEE autoneg by defaultClaudiu Manoil
This controller does not support EEE, but it may connect to a PHY which supports EEE and advertises EEE by default, while its link partner also advertises EEE. If this happens, the PHY enters low power mode when the traffic rate is low and causes packet loss. This patch disables EEE advertisement by default for any PHY that gianfar connects to, to prevent the above unwanted outcome.

2017-12-12sdk_dpaa: ceetm: stop transmitting frames when the CQ is congestedCamelia Groza
When the egress CQ is congested, drop the frames instead of enqueueing them. This is more efficient than enqueueing and receiving them back on the ERN queue. We also can't stop the netdev queues because that would affect all the CQs and would hinder prioritization. Signed-off-by: Camelia Groza <camelia.groza@nxp.com>

2017-12-12dpaa_eth: use AVOIDBLOCK for Tx confirmation queuesMadalin Bucur
The AVOIDBLOCK flag determines the Tx confirmation queues processing to be redirected to any available CPU when the current one is slow in processing them. This may result in a higher Tx confirmation interrupt count but may reduce pressure on a certain CPU that with the previous setting would process all Tx confirmation frames.

2017-12-12dpaa_eth: enable multiple Tx traffic classesCamelia Groza
Implement the setup_tc ndo to configure prioritised Tx traffic classes. Priorities range from 0 (lowest) to 3 (highest). The driver assigns NR_CPUS queues to each traffic class. Signed-off-by: Camelia Groza <camelia.groza@nxp.com> Signed-off-by: Madalin Bucur <madalin.bucur@nxp.com>
2017-12-12dpaa_eth: add four prioritised Tx traffic classesCamelia Groza
Each traffic class corresponds to a WQ priority level. The number of Tx netdev queues and frame queues is increased to NR_CPUS queues for each traffic class. In addition, the priority of the Rx, Error and Conf queues is lowered but their order is maintained. By default, only one traffic class is enabled, only the low priority Tx queues are used and only the corresponding netdev queues are advertised.
