145 * the data to non-longword aligned. Since IP requires the
146 * data to be longword aligned, we need to copy it after it has

148 *
149 * Since we have to copy it anyways, we might as well as allocate

155 * And the number of receive descriptors multiplied by the size
156 * of the receive buffers must equal the recevive space. This
157 * is so that we can manipulate the page tables so that even if a
158 * packet wraps around the end of the receive space, we can
159 * treat it as virtually contiguous.

161 * The above used to be true (the stupid restriction is still true)
