Xilinx TSN (time sensitive networking) TEMAC axi ethernet driver (xilinx_axienet)
-----------------------------------------------------------------------
Required properties:
- compatible : Should be "xlnx,tsn-ethernet-1.00.a".
- reg : Physical base address and size of the TSN registers map.
- interrupts : Property with a value describing the interrupt
number.
- interrupts-names : Property denotes the interrupt names.
- interrupt-parent : Must be core interrupt controller.
- phy-handle : See ethernet.txt file [1].
- local-mac-address : See ethernet.txt file [1].
- phy-mode : see ethernet.txt file [1].
Optional properties:
- xlnx,tsn : Denotes a ethernet with TSN capabilities.
- xlnx,tsn-slave : Denotes a TSN slave port.
- xlnx,txcsum : Tx checksum mode (Full, Partial and None).
- xlnx,rxcsum : Rx checksum mode (Full, Partial and None).
- xlnx,phy-type : Xilinx phy device type. See xilinx-phy.txt [2].
- xlnx,eth-hasnobuf : Used when 1G MAC is configured in non-processor mode.
- xlnx,num-queue : Number of queue supported in current design, range is
2 to 5 and default value is 5.
- xlnx,num-tc : Number of traffic class supported in current design,
range is 2,3 and default value is 3. It denotes
the traffic classes based on VLAN-PCP value.
- xlnx,qbv-addr : Denotes mac scheduler physical base address.
- xlnx,qbv-size : Denotes mac scheduler address space size.
