Hi, this series adds a DSA driver for the Hirschmann Hellcreek TSN switch IP. Characteristics of that IP: * Full duplex Ethernet interface at 100/1000 Mbps on three ports * IEEE 802.1Q-compliant Ethernet Switch * IEEE 802.1Qbv Time-Aware scheduling support * IEEE 1588 and IEEE 802.1AS support That IP is used e.g. in https://www.arrow.com/en/campaigns/arrow-kairos Due to the hardware setup the switch driver is implemented using DSA. A special tagging protocol is leveraged. Furthermore, this driver supports PTP, hardware timestamping and TAPRIO offloading. This work is part of the AccessTSN project: https://www.accesstsn.com/ If there are any objections let me know.
