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