160  * the data to non-longword aligned.  Since IP requires the
161  * data to be longword aligned, we need to copy it after it has
162  * been DMA'ed in our memory.
163  *
164  * Since we have to copy it anyways, we might as well as allocate
165  * dedicated receive space for the input.  This allows to use a
166  * small receive buffer size and more ring entries to be able to
167  * better keep with a flood of tiny Ethernet packets.
168  *
169  * The receive space MUST ALWAYS be a multiple of the page size.
170  * And the number of receive descriptors multiplied by the size
171  * of the receive buffers must equal the recevive space.  This
172  * is so that we can manipulate the page tables so that even if a
173  * packet wraps around the end of the receive space, we can
174  * treat it as virtually contiguous.
175  *
176  * The above used to be true (the stupid restriction is still true)

178  * architecture which can't handle unaligned accesses) because with
179  * 100Mb/s cards the copying is just too much of a hit.
