Modified files:
sys/dev/hme if_hme.c if_hmereg.h if_hmevar.h
Log:
Convert to use bus_dmamap_load_mbuf(); decouple software TX descriptors
from the hardware descriptors to avoid the overhead of having a DMA
map for each of them. Bump the number of hardware descriptors to 128,
and use half as many software descriptors for now.
Some minor cleanups.
