Bill Paul 141ae16656 Add support for still more cheapo 10/100 cards: Delta Electronics and
Addtron appear to have their own VIA Rhine II and RealTek 8139 boards
with custom PCI vendor and device IDs. This commit updates the PCI
vendor and device lists in the vr and rl drivers so that we can probe
the additional devices.

* RESET: 1 == software reset, 0 == normal operation

* 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

*
* 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.
