Added full Layer 2 support to NimPacket. You can now build Ethernet frames and ARP packets.

What's New

Ethernet Headers


let frame = (EthernetHeader(
  destMAC: parseMAC("00:11:22:33:44:55"),
  srcMAC: parseMAC("AA:BB:CC:DD:EE:FF"),
  etherType: ETHERTYPE_IPV4
) / ipv4 / tcp).toBytes()

ARP Packets


let arpRequest = (ethernet / newARPRequest(
  myMAC, myIP, targetIP
)).toBytes()

Use Cases

Network scanners with ARP

Complete packet crafting from Layer 2

Traffic generation tools

Security research and testing

Examples

Added two new demo files in examples/:

ethernet_demo.nim - Ethernet frame examples

arp_demo.nim - ARP packet examples

Run them to see how it works.

Testing

83 tests, all passing.
