Ike has since done some more extensive testing, and found that performance actually *drops* with longer iperf runs. With a 900s run, he's seeing it go down to ~200Mbps, while the kernel emits messages like these:

    [ 1070.047048] ITS queue timeout (65440 65504 1120)
    [ 1070.051658] ITS cmd its_build_inv_cmd failed

It's unclear if this is actually an issue with the patch, or a platform-specific issue, but either way I think we need to change this status to verification-failed. I've reported this upstream.
