+Subject: [PATCH] brcmfmac: set wiphy's addresses to provide valid MACs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Broadcom's firmware requires every BSS to use MAC address with unique
+last few bits. The amount of bits may depend on a particular firmware,
+it was verified to be 2 for BCM43602 one.
+If this condition won't be fulfilled firmware will reject such MAC:
+brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52
+
+We don't want to simply set addr_mask as it would also disallow using
+locally administrated bit. Instead let's build a list of addresses
+manually enabling 0x2 bit for extra interfaces.
