95 * While 21x4x allows chaining of its descriptors, this driver
96 * doesn't take advantage of it. We keep the descriptors in a
97 * traditional FIFO ring.

103 tulip_desc_t *ri_nextout; /* next to processed by adapter */
109 * The 21040 has a stupid restriction in that the receive
110 * buffers must be longword aligned. But since Ethernet
111 * headers are not a multiple of longwords in size this forces
112 * the data to non-longword aligned. Since IP requires the
113 * data to be longword aligned, we need to copy it after it has
114 * been DMA'ed in our memory.
116 * Since we have to copy it anyways, we might as well as allocate
117 * dedicated receive space for the input. This allows to use a
118 * small receive buffer size and more ring entries to be able to
119 * better keep with a flood of tiny Ethernet packets.
121 * The receive space MUST ALWAYS be a multiple of the page size.
122 * And the number of receive descriptors multiplied by the size
123 * of the receive buffers must equal the recevive space. This
124 * is so that we can manipulate the page tables so that even if a
125 * packet wraps around the end of the receive space, we can
126 * treat it as virtually contiguous.
128 * The above used to be true (the stupid restriction is still true)
129 * but we gone to directly DMA'ing into MBUFs (unless it's on an
130 * architecture which can't handle unaligned accesses) because with
131 * 100Mb/s cards the copying is just too much of a hit.
