hrm.  The transceiver claims that it can't do full duplex.

What happens if you cheat, and, in vortex_probe1(), add:

        } else {
            vp->advertising = mdio_read(dev, vp->phys[0], 4);
+	    vp->advertising |= 0x0140;
            if (vp->full_duplex) {
                /* Only advertise the FD media types. */
                vp->advertising &= ~0x02A0;
                mdio_write(dev, vp->phys[0], 4, vp->advertising);
            }
