Remove ~60 unneeded #include <sys/malloc.h>
AMD AM79c873 have identical registers. I'm not sure why; one is probably a clone of the other.
this PHY and the Davicom DM9101 have exactly the same register definitions. One of them is probably a clone of the other. I'm not sure which. This is needed for the Davicom DM9102 10/100 PCI ethernet driver which will be committed shortly.
