Subject: Aw: Re:  Re: [PATCH 0/8] adding multiple CPU-Ports

Hi,

have tested only my dsa-Patches (no ethernet-changes), and what should i say...it seems to work well. second gmac is recognized, i can have traffic on both and iperf works...without any crash (tried 5 port changes with iperf between).
