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. > L3 checksum offload = Y > L4 checksum offload = Y > Timestamp offload = Y > diff --git a/doc/guides/rel_notes/release_26_07.rst > b/doc/guides/rel_notes/release_26_07.rst > index cf79eb57bf..d864019244 100644 > --- a/doc/guides/rel_notes/release_26_07.rst > +++ b/doc/guides/rel_notes/release_26_07.rst > @@ -139,6 +139,7 @@ New Features > > * Added support for transmitting LLDP packets based on mbuf packet type. > * Implemented AVX2 context descriptor transmit paths. > + * Added support for QinQ offloading operations.
