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.
