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!
This work is part of the AccessTSN project: https://www.accesstsn.com/
