Jiri Pirko a5fcf8a6c9 net: propagate tc filter chain index down the ndo_setup_tc call
We need to push the chain index down to the drivers, so they have the
information to which chain the rule belongs. For now, no driver supports
multichain offload, so only chain 0 is supported. This is needed to
prevent chain squashes during offload for now. Later this will be used
to implement multichain offload.

Madalin Bucur 58b7bd0f4b dpaa_eth: use AVOIDBLOCK for Tx confirmation queues
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.

Amritha Nambiar 56f36acd21 mqprio: Modify mqprio to pass user parameters via ndo_setup_tc.
The configurable priority to traffic class mapping and the user specified
queue ranges are used to configure the traffic class, overriding the
hardware defaults when the 'hw' option is set to 0. However, when the 'hw'
option is non-zero, the hardware QOS defaults are used.

This patch makes it so that we can pass the data the user provided to
ndo_setup_tc. This allows us to pull in the queue configuration if the
user requested it as well as any additional hardware offload type
requested by using a value other than 1 for the hw value.

Finally it also provides a means for the device driver to return the level
supported for the offload type via the qopt->hw value. Previously we were
just always assuming the value to be 1, in the future values beyond just 1
may be supported.

Camelia Groza 2ea08f8261 dpaa_eth: enable multiple Tx traffic classes
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.

Camelia Groza c44efa1d75 dpaa_eth: add four prioritised Tx traffic classes
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.

stephen hemminger bc1f44709c net: make ndo_get_stats64 a void function
The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.

Fix all drivers with ndo_get_stats64 to have a void function.
