Peter Wemm 28c412b0e9 malloc() the rx and tx descriptors seperately rather than as part of the 
large (over 4KB) softc struct.  The descriptor array is accessed by
busmaster dma and must be physically contiguous in memory.  malloc() of
a block greater than a page is only virtually contiguous, and not
necessarily physically contigious.

contigmalloc() could do this, but that is a bit on the overkill side.

I'm not sure of the origins of the problem report and diagnosis, I learned
of the problem via mail forwarded from  Jim Shankland <jas@flyingfox.com>.

Jim said that Matt Thomas's workaround was to reduce the number of
transmit descriptors from 128 to 32, but I was concerned that it might
cost performance.  Anyway, this change is my fault, not Jim's. :-)
