The Devicetree Specification, Release v0.3 specifies in section 4.3.1
a "Network Class Binding". This covers MAC address and maximal frame
size properties. "local-mac-address" and "mac-address" with a fixed
"address-size" of 48 bits are already in the ethernet-controller.yaml
schema so move those over.

Keep "address-size" fixed to 48 bits as it's unclear if network protocols
using 64-bit mac addresses like ZigBee, 6LoWPAN and others are relevant for
this binding. This allows mac address array size validation for ethernet
and wireless lan devices.

"max-frame-size" in the Devicetree Specification is written to cover the
whole layer 2 ethernet frame but actual use for this property is the
payload size. Keep the description from ethernet-controller.yaml which
specifies the property as MTU.

Changes in v4:
- Changed the mailing list address (Rob)
- Copyied the whole description for the max-frame-size, including the
  MTU x max-frame-size contradiction. (Rob)
- Link to v3: https://lore.kernel.org/r/20250318-dt-bindings-network-class-v3-0-4d8d04ddfb61@ixit.cz

Changes in v3:
- Incorporated wireless-controller.yaml suggestion (Andrew)
- Link to v2: https://lore.kernel.org/r/20230203-dt-bindings-network-class-v2-0-499686795073@jannau.net

Changes in v2:
- Added "max-frame-size" with the description from ethernet-controller.yaml
- Restrict "address-size" to 48-bits
- Fix the mac-address array size to 6 bytes
- Drop duplicate default value from "max-frame-size" description
- Link to v1: https://lore.kernel.org/r/20230203-dt-bindings-network-class-v1-0-452e0375200d@jannau.net
