Subject: [PATCH net-next v8 0/8] Hirschmann Hellcreek DSA driver
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 work is part of the AccessTSN project: https://www.accesstsn.com/
