-/**
- * ath5k_hw_set_bssid_mask - filter out bssids we listen
- *
- * @ah: the &struct ath5k_hw
- * @mask: the bssid_mask, a u8 array of size ETH_ALEN
- *
- * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
- * which bits of the interface's MAC address should be looked at when trying
- * to decide which packets to ACK. In station mode and AP mode with a single
- * BSS every bit matters since we lock to only one BSS. In AP mode with
- * multiple BSSes (virtual interfaces) not every bit matters because hw must
- * accept frames for all BSSes and so we tweak some bits of our mac address
- * in order to have multiple BSSes.
- *
- * NOTE: This is a simple filter and does *not* filter out all
- * relevant frames. Some frames that are not for us might get ACKed from us
- * by PCU because they just match the mask.
- *
- * When handling multiple BSSes you can get the BSSID mask by computing the
- * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
- *
- * When you do this you are essentially computing the common bits of all your
- * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
- * the MAC address to obtain the relevant bits and compare the result with
- * (frame's BSSID & mask) to see if they match.
- */
-/*
- * Simple example: on your card you have have two BSSes you have created with
- * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
- * There is another BSSID-03 but you are not part of it. For simplicity's sake,
- * assuming only 4 bits for a mac address and for BSSIDs you can then have:
- *
- *                  \
- * MAC:                0001 |
- * BSSID-01:   0100 | --> Belongs to us
- * BSSID-02:   1001 |
- *                  /
- * -------------------
- * BSSID-03:   0110  | --> External
- * -------------------
- *
- * Our bssid_mask would then be:
- *
- *             On loop iteration for BSSID-01:
- *             ~(0001 ^ 0100)  -> ~(0101)
- *                             ->   1010
- *             bssid_mask      =    1010
- *
- *             On loop iteration for BSSID-02:
- *             bssid_mask &= ~(0001   ^   1001)
- *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
- *             bssid_mask =   (1010)  & ~(1001)
- *             bssid_mask =   (1010)  &  (0110)
- *             bssid_mask =   0010
- *
- * A bssid_mask of 0010 means "only pay attention to the second least
- * significant bit". This is because its the only bit common
- * amongst the MAC and all BSSIDs we support. To findout what the real
- * common bit is we can simply "&" the bssid_mask now with any BSSID we have
- * or our MAC address (we assume the hardware uses the MAC address).
- *
- * Now, suppose there's an incoming frame for BSSID-03:
- *
- * IFRAME-01:  0110
- *
- * An easy eye-inspeciton of this already should tell you that this frame
- * will not pass our check. This is beacuse the bssid_mask tells the
- * hardware to only look at the second least significant bit and the
- * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
- * as 1, which does not match 0.
- *
- * So with IFRAME-01 we *assume* the hardware will do:
- *
- *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
- *  --> allow = (0010) == 0000 ? 1 : 0;
- *  --> allow = 0
- *
- *  Lets now test a frame that should work:
- *
- * IFRAME-02:  0001 (we should allow)
- *
- *     allow = (0001 & 1010) == 1010
- *
- *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
- *  --> allow = (0010) == (0010)
- *  --> allow = 1
- *
- * Other examples:
- *
- * IFRAME-03:  0100 --> allowed
- * IFRAME-04:  1001 --> allowed
- * IFRAME-05:  1101 --> allowed but its not for us!!!

+/**
+ * ath_hw_set_bssid_mask - filter out bssids we listen
+ *
+ * @common: the ath_common struct for the device.
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ *
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:        0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (0001 & 1010) == 1010
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0010) == (0010)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

+IWCONFIG COMMANDS
+========================
+power period
+
+        This command is used to configure the station in deep sleep mode /
+        auto deep sleep mode.
+
+        The timer is implemented to monitor the activities (command, event,
+        etc.). When an activity is detected station will exit from deep
+        sleep mode automatically and restart the timer. At timer expiry
+        (no activity for defined time period) the deep sleep mode is entered
+        automatically.
+
+        Note: this command is for SDIO interface only.
+
+        Usage:
+        To enable deep sleep mode do:
+                iwconfig wlan0 power period 0
+        To enable auto deep sleep mode with idle time period 5 seconds do:
+                iwconfig wlan0 power period 5
+        To disable deep sleep/auto deep sleep mode do:
+                iwconfig wlan0 power period -1
