4.3 dmf driver that works with emulex boards

[Melvin Ferentz]

While waiting for the updated proms from Emulex, the following one line
hack will work.

dmf.c
72c72
< int	dmf_mindma = 4;			/* don't dma below this point */
---
> int	dmf_mindma = 20000; /* HACK FOR NO DMA    don't dma below this point */

The driver then works like the 4.2bsd driver, i.e. no dma.
