Subject: [PATCH v2 0/4] dt-bindings: net: Add network-class.yaml schema
Date: Sun, 12 Feb 2023 13:16:28 +0100	[thread overview]
Message-ID: <20230203-dt-bindings-network-class-v2-0-499686795073@jannau.net> (raw)

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.

Signed-off-by: Janne Grunau <j@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
- Fix 2 nios2 dts files which incorrectly use the ethernet frame size of 1518
- Link to v1: https://lore.kernel.org/r/20230203-dt-bindings-network-class-v1-0-452e0375200d@jannau.net
