+Subject: [PATCH] brcmfmac: check all combinations when setting wiphy's
+ addresses
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Broadcom is working on better reflection of interface combinations. With
+upcoming patches we may have 1st combination supporting less interfaces
+than others.
+To don't run out of addresses check all combinations to find the one
+with the greatest max_interfaces value.
