[ Upstream commit 59c2a30d36c8ae430d26a902c4c9665ea33ccee5 ]
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.
