Support In-situ Operation Administration and Maintenance (IOAM)

Brief description

I would like to contribute CMCC IOAM protocol to scapy. Partly of the IOAM layer has been implemented. I hope everyone who are interested in this can join us to enhance it.

In-situ Operation Administration and Maintenance (IOAM)

Notice: This is China Mobile Communications Corporation (CMCC) IOAM, instead of Cisco IOAM
