+Subject: [PATCH 2/8] Bluetooth: Fix attempting to set RPA timeout when
+ unsupported
+
+During controller initialization, an LE Set RPA Timeout command is sent
+to the controller if supported. However, the value checked to determine
+if the command is supported is incorrect. Page 1921 of the Bluetooth
+Core Spec v5.2 shows that bit 2 of octet 35 of the Supported_Commands
+field corresponds to the LE Set RPA Timeout command, but currently
+bit 6 of octet 35 is checked. This patch checks the correct value
+instead.
+
+This issue led to the error seen in the following btmon output during
+initialization of an adapter (rtl8761b) and prevented initialization
+from completing.
+
+< HCI Command: LE Set Resolvable Private Address Timeout (0x08|0x002e) plen 2
+ Timeout: 900 seconds
+> HCI Event: Command Complete (0x0e) plen 4
+ LE Set Resolvable Private Address Timeout (0x08|0x002e) ncmd 2
+ Status: Unsupported Remote Feature / Unsupported LMP Feature (0x1a)
+= Close Index: 00:E0:4C:6B:E5:03
+
+The error did not appear when running with this patch.
