RPI2 network performance

[fbsdarm at openmailbox.org]

Hello,

I can not get more than 10Mbps down on an RPI2. Test have been done 
through both the default fast-ethernet port and a couple of USB network 
adapter (different chipsets).
All recognized but all stuck at 10Mbps max. I've used curl to /dev/null 
for the test. (to exclude potential SDCard limit).I am running 
11.0-ALPHA2.

Is there any trick needed to get 100Mbps pass-through? (Just want to use 
it as a gateway/firewall).
Thanks,
