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. "net: dsa: add Arrow SpeedChips XRS700x driver" depends on: "net: dsa: add optional stats64 support" being merged first. https://lore.kernel.org/netdev/20201204145624.11713-2-o.rempel@xxxxxxxxxxxxxx/ Changes since v1: * Use central TX reallocation in tag driver. (Andrew Lunn) * Code style fixes. (Andrew Lunn, Vladimir Oltean) * Code simplifications. (Andrew Lunn, Vladimir Oltean) * Verify detected switch matches compatible. (Andrew Lunn) * Add inbound policy to allow BPDUs. (Andrew Lunn) * Move files into their own subdir. (Vladimir Oltean) * Automate regmap field allocation. (Vladimir Oltean) * Move setting link speed to .mac_link_up. (Vladimir Oltean) * Use different compatible strings for e/f variants. Changes since v2: * Export constant xrs700x_info symbols. (Jakub Kicinski) * Report stats via .get_stats64. (Jakub Kicinski, Vladimir Oltean) * Use a 3 second polling rate for counters.
