+Subject: [PATCH] brcmfmac: increase buffer for obtaining firmware capabilities
+
+When obtaining the firmware capability a buffer is provided of 512
+bytes. However, if all features in firmware are supported the buffer
+needs to be 565 bytes as otherwise truncated information is retrieved
+from firmware. Increasing the buffer to 768 bytes on stack.
