Low level analyzer

I use Wireshark for analyzing the network traffic. I identified a lot of re-transmissions caused by packet loss on a device that is connected to a 10 MBit/s hub or switch. If the same device is connected to a 100 MBit/s switch, it works normally. Wireshark uses a packet capture library (e.g. Winpcap for Windows) that captures all packets visible to the network controller driver. But there is also the low level communication that is responsible to perform the speed and mode negotiation between hub and PHY (and probably between PHY and MAC controller). Do you know any tool that can be used to investigate what's going on here? It would be sufficient to look at the 10 MBit/s connection. Is there an documentation or guide line how to attack such a problem?
