Hi,

  I am trying to write a PCI ethernet driver for FreeBSD 3.4 release . I
am new to the driver stuff.

   I want to allocate some memory for device buffer  using malloc
function. I also want the physical address of allocated  memory block
so that I can initialize the device registers.

   Can any one of you please explain me how I can convert address
returned by
malloc to Physical address.

Thanks
-Pran
