Ability to use tools like Scapy to add headers for unsupported protocols.

How to add headers for unsupported protocols.

• Unsupported protocols can be added using custom packet header.
• A custom packet header is defined as a string of hex bytes.The string MUST contain sequence of valid hex bytes.Spaces or colons can be part of the bytes but will be discarded.

Example of adding ARP header as custom header.

import pytest
import snappi
from scapy.all import *


def test_scapy(api):
    pkt = ARP(hwtype=1, ptype=0x0800)
    config = api.config()  # type: snappi.config.Config
    (p1,) = config.ports.port(name="p1")
    (f1,) = config.flows.flow(name="p1")
    f1.tx_rx.port.tx_name = p1.name
    (custom,) = f1.packet.custom()
    custom.bytes = scapy.utils.repr_hex(pkt.__bytes__())
    print(config)


if __name__ == "__main__":
    pytest.main(["-s", __file__])
