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

104 tulip_desc_t *ri_nextout; /* next to processed by adapter */
110 * The 21040 has a stupid restriction in that the receive
111 * buffers must be longword aligned. But since Ethernet
112 * headers are not a multiple of longwords in size this forces
113 * the data to non-longword aligned. Since IP requires the
114 * data to be longword aligned, we need to copy it after it has
115 * been DMA'ed in our memory.
117 * Since we have to copy it anyways, we might as well as allocate
118 * dedicated receive space for the input. This allows to use a
119 * small receive buffer size and more ring entries to be able to
120 * better keep with a flood of tiny Ethernet packets.
122 * The receive space MUST ALWAYS be a multiple of the page size.
123 * And the number of receive descriptors multiplied by the size
124 * of the receive buffers must equal the recevive space. This
125 * is so that we can manipulate the page tables so that even if a
126 * packet wraps around the end of the receive space, we can
127 * treat it as virtually contiguous.
129 * The above used to be true (the stupid restriction is still true)
130 * but we gone to directly DMA'ing into MBUFs (unless it's on an
131 * architecture which can't handle unaligned accesses) because with
132 * 100Mb/s cards the copying is just too much of a hit.
