167 * key to the stream ID is 0x43244. I can use the DMA address of the TRB to
168 * pass the radix tree a key to get the right stream ID:
179 * The radix tree uses an unsigned long as a key pair. On 32-bit systems, an
182 * key on 32-bit or 64-bit systems (it would also be fine if we asked for 64-bit
