Documentation update

[DmitriKh]

Example given in "Automatically decoding layers" shows

eth_frame = ethernet.Ethernet(capfile.packets[0].raw())
wifi_frame = wifi.WIFI(capfile.packets[1].raw())
print(eth_frame)
ethernet from 00:11:22:33:44:55 to ff:ee:dd:cc:bb:aa type IPv4
print(wifi_frame)
QoS data (sa: None, ta: 00:11:22:33:44:55, ra: ff:ee:dd:cc:bb:aa, da: None)
ip_packet = ip.IP(eth_frame.payload)
print(ip_packet)

When tested on python 3.9.x the example requires additional "binascii.unhexlify" to create IP packet from Ethernet and UDP from IP.
ip_packet = ip.IP(binascii.unhexlify(eth_frame.payload))
udp_frame = udp.UDP(binascii.unhexlify(ip_packet.payload))

This seems more like a bug than a documentation issue.

I was trying to reproduce this issue, but both samples/test.pcap and test/test_data/test.pcap seem to be missing.

Are you able to provide the code you ran (was it just the example code) and the test.pcap file you were using (in case that makes a difference)?
