The 'mii-diag' output would be useful here, but we can see most of the
MII-like registers from this output.

The MII registers are
1000 782d .... .... 0101 0000

You are advertising only 10baseT-HDX!  No wonder the link is at 10Mbps.

This should only happen in two cases:
  You use 'mii-diag' to force the media type.
  You pass a media type option to the driver.

The v1.13 driver should log the following message if the latter is the
case:
	printk(KERN_INFO "  Forcing %dMbs %s-duplex operation.\n",
		   (option & 0x20 ? 100 : 10),
		   (option & 0x10 ? "full" : "half"));
Read the driver detection message from 'dmesg'.
