• Virtual LAN (VLAN) Support
• Link Layer Discovery Protocol
• IEEE 802.1Qav

Overview

Ethernet is a networking technology commonly used in local area networks (LAN). For more information, see this Ethernet Wikipedia article.

Zephyr supports following Ethernet features:

• 10, 100 and 1000 Mbit/sec links

• Auto negotiation

• Half/full duplex

• Promiscuous mode

• TX and RX checksum offloading

• MAC address filtering

• Virtual LANs

• Priority queues

• IEEE 802.1AS (gPTP)

• IEEE 802.1Qav (credit based shaping)

• LLDP (Link Layer Discovery Protocol)

Not all Ethernet device drivers support all of these features. You can see what is supported by net iface net-shell command. It will print currently supported Ethernet features.
