| 323 | * @agg_disable_start_th: try-count threshold for starting aggregation. |
| 324 | * If a frame has higher try-count, it should not be selected for |
| 325 | * starting an aggregation sequence. |
| 326 | * @agg_frame_cnt_limit: max frame count in an aggregation. |
| 327 | * 0: no limit |
| 328 | * 1: no aggregation (one frame per aggregation) |
| 329 | * 2 - 0x3f: maximal number of frames (up to 3f == 63) |
| 330 | * @rs_table: array of rates for each TX try, each is rate_n_flags, |
| 331 | * meaning it is a combination of RATE_MCS_* and IWL_RATE_*_PLCP |
| 332 | * @bf_params: beam forming params, currently not used |
