Dmitry Borisov 59d8a77df6
[DC21X4] Add driver for DECchip 21x4-compatible network adapters (#5614) 
These adapters were common in DEC Alpha boxes and they are really rare
nowadays. The 21140 chip is emulated in Connectix / Microsoft Virtual PC
and Hyper-V Gen 1 VM.

This is an experimental driver, not yet tested on real hardware.
