Hi Felix,

I've build an image for the reporter of FS#27 for testing and received
the following response:

> I upgraded existing HH5A with r1228, with your new SMP.bin file.  Enabled
> WAN port as DHCP client, wired to LAN port of my main router.
>
> I am still seeing TX ring full messages on console, but one key improvement
>
> When testing the images in June with SMP enabled, the internet connection
> would just cease functioning between 10 and 30 seconds after HH5A connects
> to my LAN using the red WAN port when traffic passed through it.
>
> Using your new image, I can continue to work on internet.  See attached
> jpegs and log file.  Previously in June, I would not have been able to get
> as far as starting the speedtest.net.
