-/**
- * ath5k_hw_set_bssid_mask - set common bits we should listen to
- *
- * The bssid_mask is a utility used by AR5212 hardware to inform the hardware
- * which bits of the interface's MAC address should be looked at when trying
- * to decide which packets to ACK. In station mode every bit matters. In AP
- * mode with a single BSS every bit matters as well. In AP mode with
- * multiple BSSes not every bit matters.
- *
- * @ah: the &struct ath5k_hw
- * @mask: the bssid_mask, a u8 array of size ETH_ALEN
- *
- * Note that this is a simple filter and *does* not filter out all
- * relevant frames. Some non-relevant frames will get through, probability
- * jocks are welcomed to compute.
- *
- * When handling multiple BSSes (or VAPs) you can get the BSSID mask by
- * computing the set of:
- *
- * ~ ( MAC XOR BSSID )
- *
- * When you do this you are essentially computing the common bits. Later it
- * is assumed the harware will "and" (&) the BSSID mask with the MAC address
- * to obtain the relevant bits which should match on the destination frame.
- *
- * 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!!!

+ * 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!!!
