171 * the data to non-longword aligned. Since IP requires the
172 * data to be longword aligned, we need to copy it after it has
173 * been DMA'ed in our memory.
174 *
175 * Since we have to copy it anyways, we might as well as allocate
176 * dedicated receive space for the input. This allows to use a
177 * small receive buffer size and more ring entries to be able to
178 * better keep with a flood of tiny Ethernet packets.
179 *
180 * The receive space MUST ALWAYS be a multiple of the page size.
181 * And the number of receive descriptors multiplied by the size
182 * of the receive buffers must equal the recevive space. This
183 * is so that we can manipulate the page tables so that even if a
184 * packet wraps around the end of the receive space, we can
185 * treat it as virtually contiguous.
186 *
187 * The above used to be true (the stupid restriction is still true)
188 * but we gone to directly DMA'ing into MBUFs (unless it's on an
189 * architecture which can't handle unaligned accesses) because with
190 * 100Mb/s cards the copying is just too much of a hit.
