MCS9 introduces some corner cases in the current rs algorithm which may lead to non optimal throughput and instability in the throughput. Until all the corner cases are resolved disable MCS9 for Tx as a workaround which yields better throughput results as MCS8 is much more stable.

The stop_hw trans callback is not well defined. It is missing in many cleanup flows and the division of labor between stop_device/stop_hw is cumbersome. Remove stop_hw and use stop_device to perform both. Implement this for all current transports. PCIE needs some extra configuration the op-mode is leaving to configure RF kill. Expose this explicitly as a new op_mode_leave trans callback. Take the call to stop_device outside iwl_run_mvm_init_ucode, this makes more sense and WARN when we want to run the INIT firmware while it has run already.

The smart FIFO is enabled when there is only one bound interface (other than p2p devices which are ignored) and it is of type station, and activated while the station is associated.

Products that have only 1 antenna in Rx don't support MIMO in RX. As a consequence, they will be in STATIC always. Don't tell mac80211 to update SMPS in that case. mac80211 would send an action frame to the AP which is clearly bogus. As a matter of fact, we have seen that some APs send a deauth when that happens.

Rewrite the search cycle state machine to use a more data oriented approach where the different Tx columns (configs) limitations and next columns to search are reprsented in tables which are easy to change. This overhaul also includes several major fixes: 1. Prevent going back to a specific Tx column in a search cycle if it was already explored. 2. Avoid switching to a Tx column that doesn't have any chance if it performs perfectly to beat the current throughput we're getting. These issues were degrading throughput as they were causing switching to "bad" Tx columns.

The table rs_ht_to_legacy is used to get the next legacy rate following the last HT or VHT rate in the LQ rates table. The mapping wasn't correct as well as didn't include entries for MCS8/9 which led to out of bounds access. This didn't trigger a crash but led to legacy rate entries using 1Mbps rate. In 5Ghz this probably caused the Tx to fail completely given that Tx attempt would have reached the legacy entries and 1Mbps isn't valid.
