We already increment the unicast IPACKETS and OPACKETS counters in the
rx/tx paths, respectively. Multicast packets are counted in the generic
ethernet code. Therefore, we shouldn't increment these counters in
dwc_harvest_stats().
Drop the early return from dwc_rxfinish_one() so that we still count
received packets with e.g. a checksum error.

Some board use dwc phy in MII mode, so do not fail to attach if this is
the case.
Only rockchip code uses the phy mode to program some custom syscon register.

Original if_dwc driver used m_defrag as an implementation shortcut but on
1000Mb networks it affects performance. Implement multi-descriptor support for
TX path.
Tested on RK3399-Firefly, patch adds ~15% of network throughput.

DTS node can have this property which configure the burst length
for both TX and RX if it's the same.
This unbreak if_dwc on Allwinner A20 and possibly other boards that
uses this prop.

Do not hardcode what we setup for the DMA engine configuration but
lookup the fdt properties and configuring accordingly.
Use a default value of 8 for the burst dma length for both TX and
RX, this is what we used for TX before.
- Do not rely on U-Boot for clocks configuration, enable and set frequencies
in the driver's attach method.
- Adjust MAC settings according to detected linespeed on RK3399 and RK3328.
- Add support for RMII PHY mode on RK3328.

Use naming nomenclature used in DesignWare TRM.
This driver was written by using Altera (now Intel) documentation for Arria
FPGA manual. Unfortunately this manual used very different (and in some cases
opposite naming) for registers and descriptor fields. Unfortunately,
this makes future expansion extremely hard.
Should not been functional change.

On rockchip board it seems that the value in the DTS
are not enough for reseting the chip, I don't know if
the value are really incorrect or if DELAY is not precise
enough or if the rockchip gpio driver have some "lag" of some
kind or not.
For now just add more delay.
In some cases, the driver must handle given properties located in
specific OF subnode. Instead of creating duplicate set of function, add
'node' as argument to existing functions, defaulting it to device OF node.

This also adds a newbus interface that allows a SoC to override the
following settings:
- if_dwc specific SoC initialization;
- if_dwc descriptor type;
- if_dwc MII clock.
This seems to be an old version of the hardware descriptors but it is
still in use in a few SoCs (namely Allwinner A20 and Amlogic at least).
Tested on Cubieboard2 and Banana pi.
Tested for regressions on Altera Cyclone by br@ (old version).

Previously the OACTIVE flag was being set when the tx descriptors are fully
allocated but it wasn't unset anywhere.
As soon as a packet is transmitted, unset the OACTIVE flag and call start
routine to push any pending packets from the tx queue.
This closes another race where a full tx queue would jam the tx path (tx
queue is full, new packets cannot be added to queue and dwc_txstart never
gets called).
