Some general input would be helpful in understanding the validity of
certain test cases within this suite. Each test case is based on the old
DTS test plan. As it currently exists, none of the NICs available for
testing (Intel, Broadcom, Mellanox) properly interface with ethdev api
functions related to tpid changes; some may not support it these
features.

There is a comment on the old DTS test plan related to extended vlans
that needs extra clarification:

"Due to the kernel enables Qinq and cannot be closed, the DPDK only add
`extend on` to make the VLAN filter work normally. Therefore, if the
i40e firmware version >= 8.4 the DPDK can only add `extend on` to make
the VLAN filter work normally"

Capabilities needed related to certain VLAN offloading functionalities,
and these are implemented within the test suite currently.

Some interesting points to highlight in writing this test suite is the
need to modify the tpid at the 'Ether' layer within Scapy, as doing so
modifies the correct tpid needed for testing; this might seem
counter-intuitive at first glance.
