net: add tulip (dec21143) driver

Browse source 
This adds the basic functionality to emulate a Tulip NIC.

Implemented are:

- RX and TX functionality
- Perfect Frame Filtering
- Big/Little Endian descriptor support
- 93C46 EEPROM support
- LXT970 PHY

Not implemented, mostly because i had no OS using these functions:

- Imperfect frame filtering
- General Purpose Timer
- Transmit automatic polling
- Boot ROM support
- SIA interface
- Big/Little Endian data buffer conversion

Successfully tested with the following Operating Systems:

- MSDOS with Microsoft Network Client 3.0 and DEC ODI drivers
- HPPA Linux
- Windows XP
- HP-UX
