+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:
+
+root@openrouter:/# iw phy phy0 info
+Wiphy phy0
+ Band 1:
+ (...)
+ Frequencies:
+ * 2412 MHz [1] (0.0 dBm)
+ * 2417 MHz [2] (0.0 dBm)
+ * 2422 MHz [3] (0.0 dBm)
+ * 2427 MHz [4] (0.0 dBm)
+ * 2432 MHz [5] (0.0 dBm)
+ * 2437 MHz [6] (0.0 dBm)
+ * 2442 MHz [7] (0.0 dBm)
+ * 2447 MHz [8] (0.0 dBm)
+ * 2452 MHz [9] (0.0 dBm)
+ * 2457 MHz [10] (0.0 dBm)
+ * 2462 MHz [11] (0.0 dBm)
+ * 2467 MHz [12] (0.0 dBm)
+ * 2472 MHz [13] (0.0 dBm)
+ * 2484 MHz [14] (0.0 dBm)
+ (...)
+
+To prevent this, only parse the caps on the first firmware load during
+hardware probe, and store them locally to know we have already parsed
+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.
