Module ethernet 

Ethernet protocol layer

This module provides Ethernet II frame handling for the network stack. It implements the NetworkLayer trait for Ethernet encapsulation/decapsulation.

Design

The EthernetLayer manages:

• Multiple network interfaces with their MAC addresses
• Interface selection for outgoing packets
• Device access for sending/receiving frames

This design supports multiple network interfaces (eth0, eth1, wlan0, etc.).
