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

154 * of the receive buffers must equal the recevive space. This
155 * is so that we can manipulate the page tables so that even if a
156 * packet wraps around the end of the receive space, we can
157 * treat it as virtually contiguous.
