-Takes an input u32 enum, no output.
+Unofficial name.
-The input value must be 0-1.
+Takes an input u32 '''Mode'''. No output.
-This internally sends a request which is then eventually handled (if the input doesn't match state already + other state fields are valid) by configuring "pm2_sleep_ret_ext" with a global struct selected via the input value. Afterwards another func is called with input value 2.
+'''Mode''' must be 0 or 1.
+Sends command message 0x32 to the state machine.
+The state machine then handles this by issuing the WLC_SET_VAR ioctl for the "pm2_sleep_ret_ext" variable. '''Mode''' is used to select between 2 sets of hardcoded parameters as follows:
+  struct wl_pm2_sleep_ret_ext {
+    u8 logic;
+    u8 PAD;
+    u16 low_ms;
+    u16 high_ms;
+    u16 rx_pkts_threshold;
+    u16 tx_pkts_threshold;
+    u16 txrx_pkts_threshold;
+    u32 rx_bytes_threshold;
+    u32 tx_bytes_threshold;
+    u32 txrx_bytes_threshold;
+  };
+  wl_pm2_sleep_ret_ext args = {0};
+  if (mode == 0) {
+    args.logic = 2;
+    args.low_ms = 2000;
+    args.high_ms = 5000;
+    args.rx_pkts_threshold = 10;
+  } else if (mode == 1) {
+    args.logic = 2;
+    args.low_ms = 200;
+    args.high_ms = 800;
+    args.rx_pkts_threshold = 10;
+  }
+Afterwards, the WLC_SET_PM ioctl is issued with the argument value 2 (PM2).
