Bill Paul 7ad5b08ab3 Remove the definitions for the SiS 900 chip. This is not a RealTek 
clone after all. I have the datasheets for this part; hopefully I can
write a proper driver soon.

* The RealTek doesn't use a fragment-based descriptor mechanism.

* packet buffer (32-bit aligned!) and we place the buffer addresses in
* the registers so the chip knows where they are.
*
* We can sort of kludge together the same kind of buffer management
* used in previous drivers, but we have to do buffer copies almost all
* the time, so it doesn't really buy us much.

*
* LOOPBK: 1 == loopback operation enabled, 0 == normal operation
*
* SPEEDSEL: 1 == 100Mb/s, 0 == 10Mb/s
* Link speed is selected byt his bit or if auto-negotiation if bit
* 12 (AUTONEGENBL) is set (in which case the value of this register
* is ignored).
*
* AUTONEGENBL: 1 == Autonegotiation enabled, 0 == Autonegotiation disabled
* Bits 8 and 13 are ignored when autoneg is set, otherwise bits 8 and 13
* determine speed and mode. Should be cleared and then set if PHY configured
* for no autoneg on startup.
*
* ISOLATE: 1 == isolate PHY from MII, 0 == normal operation
*
* AUTONEGRSTR: 1 == restart autonegotiation, 0 = normal operation
*
* DUPLEX: 1 == full duplex mode, 0 == half duplex mode
*
* COLLTEST: 1 == collision test enabled, 0 == normal operation
