I haven't compared performance of this patch with what if_cdce delivers, but
13.0-RELEASE's performance is not what I expected.

I have a USB dongle with RTL8156B chipset that easily gets 1.9 Gbps or 2.3 Gbps
with iPerf3 when attached to a recent Apple laptop. FreeBSD added a USB quirk
for the device to select profile 2. The device then gets 92 Mbps throughput.

If I switch it back to profile 1 using usbconfig -d ugen0.12 set_config 1, it
gets roughly 800 Mbps. The switch says the port negotiated to 2.5 Gbps in
either case.

Is there a way to achieve closer to linerate performance?
