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.

Rename PHY_INTERFACE_MODE_SGMII_2500 to PHY_INTERFACE_MODE_2500SGMII
Convention is to put the number(2500) first and then the

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.

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.

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.

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.

This should be >= instead of > here. It means that we don't increment

commit bc1f44709cf27fb2a5766cadafe7e2ad5e9cb221
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.

Update txq0's trans_start in order to prevent the netdev watchdog from

other tx queues by adding the NETIF_HW_ACCEL_MQ flag.
