124 * 32 since we don't need so many commands pending. Since the HW
125 * still uses 256 BDs for DMA though, n_bd stays 256. As a result,
126 * the software buffers (in the variables @meta, @txb in struct
127 * iwl_tx_queue) only have 32 entries, while the HW buffers (@tfds
128 * in the same struct) have 256.
129 * This means that we end up with the following:
130 *  HW entries: | 0 | ... | N * 32 | ... | N * 32 + 31 | ... | 255 |
131 *  SW entries:           | 0      | ... | 31          |
132 * where N is a number between 0 and 7. This means that the SW
