| 0x24 || 0x4 || Big-endian u32 Counter, incremented when the below content was updated. Also used by the Station to determine whether the frame changed compared to a previous one. When comparing against a previous frame, new_counter-prev_counter must be <= 0xFF, and the counters must not match.

| 0x24 || 0x4 || Big-endian u32 Counter. The initial value is randomly-generated. This is incremented each time the below content is updated (including initial creation). Also used by the Station to determine whether the frame changed compared to a previous one. When comparing against a previous frame, new_counter-prev_counter must be <= 0xFF, and the counters must not match.

| 0x28 || 0x20 || SHA256 hash over the entire frame starting at +0x0, with the above size + 0x48. During hashing, this hash is cleared, with the new hash overwriting the original in memory (the original is copied to stack for comparing).
