   3 Subject: [PATCH] brcmfmac: increase buffer for obtaining firmware capabilities
   4
   5 When obtaining the firmware capability a buffer is provided of 512
   6 bytes. However, if all features in firmware are supported the buffer
   7 needs to be 565 bytes as otherwise truncated information is retrieved
   8 from firmware. Increasing the buffer to 768 bytes on stack.
