Not sure we can advertise full support. Checking with AI it seems we have
some gaps, for example, the legacy (non-flex) descriptor scalar Rx - used
with X710 NICs for example - doesn't support reading two tags for QinQ
strip.

Can we tighten this statement up a bit - "Added support for Tx QinQ
offload", to make it clear that it's only the Tx side support has changed
in this release?
