That port is usually connected to an Ethernet Controller of the 17 SoC. Such setups are typical for embedded devices. 18 19select: false 20 21$ref: /schemas/net/ethernet-switch.yaml# 22 23properties: 24 dsa,member: 25 minItems: 2 26 maxItems: 2 27 description: 28 A two element list indicates which DSA cluster, and position within the 29 cluster a switch takes. <0 0> is cluster 0, switch 0. <0 1> is cluster 0, 30 switch 1. <1 0> is cluster 1, switch 0. A switch not part of any cluster 31 (single device hanging off a CPU port) does not usually need to specify 32 this property, and then it becomes cluster 0, switch 0. For a topology 33 aware switch, its switch index can be specified through this property, 34 even if it is not part of any cluster. Also, topology-unaware switches 35 must always be defined as index 0 of their cluster. 36 $ref: /schemas/types.yaml#/definitions/uint32-array 37 38additionalProperties: true 39 40$defs: 41 ethernet-ports: 42 description: A DSA switch without any extra port properties 43 $ref: '#' 44 45 patternProperties: 46 "^(ethernet-)?ports$": 47 patternProperties: 48 "^(ethernet-)?port@[0-9a-f]+$": 49 description: Ethernet switch ports 50 $ref: dsa-port.yaml# 51 unevaluatedProperties: false 52 53oneOf: 54 - required: 55 - ports 56 - required: 57 - ethernet-ports 58 59... 60
