127 * the software buffers (in the variables @meta, @txb in struct
128 * iwl_tx_queue) only have 32 entries, while the HW buffers (@tfds
129 * in the same struct) have 256.
130 * This means that we end up with the following:
131 *  HW entries: | 0 | ... | N * 32 | ... | N * 32 + 31 | ... | 255 |
132 *  SW entries:           | 0      | ... | 31          |
