Subject: [PATCH net-next 0/3] Arrow SpeedChips XRS700x DSA Driver

This series adds a DSA driver for the Arrow SpeedChips XRS 7000 series
of HSR/PRP gigabit switch chips.

The chips use Flexibilis IP.
More information can be found here:
 https://www.flexibilis.com/products/speedchips-xrs7000/

The switches have up to three RGMII ports and one MII port and are
managed via mdio or i2c. They use a one byte trailing tag to identify
the switch port when in managed mode so I've added a tag driver which
implements this.

This series contains minimal DSA functionality which may be built upon
in future patches. The ultimate goal is to add HSR and PRP
(IEC 62439-3 Clause 5 & 4) offloading with integration into net/hsr.
