How to send UDP packet to specific UDP dst port in scapy?

Question

I would like to send my packet to a UDP dst port number and send it through eth0 interface (if scapy handles my layer2 directly, then eth0 does not need to be given as an argument)

Answer 1

Using the scapy documentation, we see that sending an UDP packet is as simple as:

send(IP(dst="127.0.0.1")/UDP(dport=123)/Raw(load="abc"))
