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 and hardware timestamping. This version implements the DSA configure_vlan_while_not_filtering behavior by caching any VLAN requests when vlan_filtering is not set and restoring it as soon as it is. Due to the lack of a port forwarding matrix in hardware, VLANs are used to reflect the initial DSA/switchdev port separation. Patch two is the only one which changed and has to be re-reviewed. Thanks!
