It doesn’t reproduce between between 2x APU2c4 (4 hardware queues and igb driver w/ mq support), but that’s 1Gbit, plus this Mellanox thing appears to have all sorts of hardware whatnots if this is the right device:


I noticed it has support for some link-layer congestion notification I’d not heard of until now (802.1Qau, https://www.ietf.org/proceedings/67/slides/tsvarea-2.pdf).
