This test evaluates the IOAM insertion for IPv6 by checking the IOAM data
integrity on the receiver.
The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between)
and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only,
which means not on the reverse path. When Gamma is the destination, Alpha
adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the
trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM
data integrity is checked on Gamma, by comparing with the pre-defined IOAM
configuration (see below).

Note: When Gamma is the destination, Alpha adds an IOAM Pre-allocated Trace
option inside a Hop-by-hop, where 164 bytes are pre-allocated for the
trace, with 123 as the IOAM-Namespace and with 0xfff00200 as the trace
type (= all available options at this time). As a result, and based on
IOAM configurations here, only both Alpha and Beta should be capable of
inserting their IOAM data while Gamma won't have enough space and will
set the overflow bit.
