Well ge00 already runs at 100Mbit, because ISP plugged me into a 100Mbit port on the switch:
        Advertised link modes:  10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Half 1000baseT/Full 
        Advertised pause frame use: No
        Advertised auto-negotiation: Yes
        Speed: 100Mb/s

They would plug me into a 1Gbit port only if I pay for 1Gbps connectivity, which is in fact only 7 EUR/month more, but its not available in my area yet :)

Good to know, not much point in purchasing 1Gbit connectivity from my ISP unless I also replace my router.
