Throttling WAN port on n66

[kneo]

As we can control the speed at which the network card operates (10 Mbps/100 Mbps/Auto negotiation, etc), is it possible to set the speed at which the WAN port of the N66 operates? By default it's a Gigabit port, but for some tests, I want to run it at 10 Mbps only (or maybe set it at auto-negotiate).

Is that possible through the command line?

I think it is auto-negotiate port by default. I have WAN port connected to VDSL2 modem, which has 10/100 Mbps port and WAN port of N66 shows as connected on 100 Mbps.
