sys/pci if_dc.c
Log:
The DC driver asks for an alignment of PAGE_SIZE for data buffers, but also
asks that each buffer be (2048 * 256) bytes long. I suspect that alignment
isn't a real requirement since busdma only recently started honoring it. The
size is also bogus. Fix both of these and stop busdma from trying to
exhaust the system memory pool with bounce pages.
