--- Comment #8 from Mark Johnston <markj@FreeBSD.org> ---
(In reply to pascal.guitierrez from comment #7)
> i'm getting 942Mb/sec and interestingly the dropped packets are limited to a single txq, which changes between each test run:

If you're testing a single flow (i.e., the default for iperf3) then all packets
would be steered to a single queue.  Otherwise you'd end up with packet
reordering.  If you have multiple flows, then that's more surprising.
