* data to be longword aligned, we need to copy it after it has
* been DMA'ed in our memory.
*
* Since we have to copy it anyways, we might as well as allocate
* dedicated receive space for the input. This allows to use a
* small receive buffer size and more ring entries to be able to
* better keep with a flood of tiny Ethernet packets.
*
* The receive space MUST ALWAYS be a multiple of the page size.
* And the number of receive descriptors multiplied by the size
* of the receive buffers must equal the recevive space. This
* is so that we can manipulate the page tables so that even if a
* packet wraps around the end of the receive space, we can
* treat it as virtually contiguous.
*
* The above used to be true (the stupid restriction is still true)
* but we gone to directly DMA'ing into MBUFs (unless it's on an
* architecture which can't handle unaligned accesses) because with
* 100Mb/s cards the copying is just too much of a hit.
