Subject: [PATCH 1/3] wifi: rtw89: set data lowest rate according to AP supported rate

From: Chih-Kang Chang <[email protected]>

By default the driver uses the 1M and 6M rate (0x0) for data frames in
2 GHz and 5/6 GHz bands respectively. But the rate that might not AP
supported. Therefore, We modify the data lowest rate according to the
lowest of AP supported rate.

Subject: [PATCH 3/3] wifi: rtw89: fix incorrect channel info during scan due to ppdu_sts filtering

From: Chih-Kang Chang <[email protected]>

We use ppdu_sts to obtain channel information from hardware, to ensure
that the scan results have correct channel information. However, some of
ppdu_sts that is filtered by the to_self check is also needed for the scan
results. Therefore, we modify the filter part in front of CFO count.

Subject: [PATCH 2/3] wifi: rtw89: remove superfluous H2C of join_info

From: Chin-Yen Lee <[email protected]>

We find that when starting WoWLAN, the second join_info H2C is
unnecessary and leads WoWLAN not enter power save mode if using new
firmware, so remove it.
