+Subject: [PATCH] mwl8k: don't overwrite regulatory settings
+
+Currently the caps are parsed on every firmware reload, causing any
+channel flags to be cleared.
+When there is a firmware to interface mode mismatch, the triggered
+firmware reload causes a reset of the regulatory settings, causing all
+channels to become available:

+them.

+Subject: [PATCH] mwl8k: always apply configuration even when device is idle
+
+Fix settings not being applied when the device is idle and the firmware
+gets reloaded (because of changing from STA to AP mode). This caused
+the device using the wrong channel (and likely band), e.g. a 5 GHz only
+card still defaulted to channel 6 in the 2.4 GHz band when left
+unconfigured.
+
+This issue was always present, but only made visible with "mwl8k: Do not
+call mwl8k_cmd_set_rf_channel unconditionally" (0f4316b9), since before
+that the channel was (re-)configured at the next _config call even when
+it did not change from the mac80211 perspective.
