113 * The 21040 has a stupid restriction in that the receive

115 * headers are not a multiple of longwords in size this forces
116 * the data to non-longword aligned. Since IP requires the
117 * data to be longword aligned, we need to copy it after it has
118 * been DMA'ed in our memory.
119 *
120 * Since we have to copy it anyways, we might as well as allocate
121 * dedicated receive space for the input. This allows to use a
122 * small receive buffer size and more ring entries to be able to
123 * better keep with a flood of tiny Ethernet packets.
124 *
125 * The receive space MUST ALWAYS be a multiple of the page size.
126 * And the number of receive descriptors multiplied by the size
127 * of the receive buffers must equal the receive space. This
128 * is so that we can manipulate the page tables so that even if a
129 * packet wraps around the end of the receive space, we can
130 * treat it as virtually contiguous.
131 *
132 * The above used to be true (the stupid restriction is still true)
133 * but we gone to directly DMA'ing into MBUFs (unless it's on an
134 * architecture which can't handle unaligned accesses) because with
135 * 100Mb/s cards the copying is just too much of a hit.
