>Description:
The if_de driver behaves somehow strange in an 164LX/533MHz machine.
There is no supported autoselect media available and the fullduplex mode
doesn't work correctly. I can manualy set the fdx bit but get pore transfer
rates with it.

The same card works fine in an i386.

Fullduplex works fine with an 3C905.

>How-To-Repeat:
Place a DLink DFE-500TX in a fast Alpha and notice that the driver knows
nothing about the autoselect mode:
de0: flags=8822<BROADCAST,NOTRAILERS,SIMPLEX,MULTICAST> mtu 1500
        address: 00:80:c8:e2:7e:74
        media: Ethernet 100baseTX
        status: active
        supported Ethernet media:
                media 100baseTX mediaopt full-duplex
                media 100baseTX
                media 10baseT mediaopt full-duplex
                media 10baseT

The same card works fine in an i386:
de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:80:c8:e2:7e:74
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        supported Ethernet media:
                media autoselect
                media 100baseTX mediaopt full-duplex
                media 100baseTX
                media 10baseT mediaopt full-duplex
                media 10baseT

The Dlink has an 21140-AF and an Level1 ST10040QC mii chip on it,
but I get the same problem with a different DLink card which has an
21140-AE and a different mii chip.

Oh, and the driver is completly broken for a 21143-PA and a ML6694 chip,
which does only work in 10MBit (that also happens on the i386 port).
>Fix:
Unknown, maybe rewrite the driver so it uses the mii layer.
