I checked with two switches, FreeBSD reports bullshit on that subject. I also realised severe problems of this Intel i350 dual NIC cards with FreeBSD (we use this NIC type as a standard and so we have plenty, all with the same issue). When the NIC negotiates its linkspeed, it very often fall back to 100 MBit. This behaviour is not predictable, but it occurs with a SoHo smart managed Netgear GS110TBv2 and some of our Cisco Catalyst switches at work (some 35XX and 29XX, I do not know the exact type).
