3.2. Meta Frame Length in Words

The Meta frame length in words parameter specifies the length of the meta frame, in 64‑bit (8‑byte) words. In the Interlaken specification, this parameter is called the MetaFrameLength parameter.

Smaller values for this parameter shorten the time to achieve lock. Larger values reduce overhead while transferring data, after lock is achieved.

For simulation, you can set the Meta frame length in words parameter to the value of 128 for fast lane locking. For hardware testing, Intel® recommends that you set the Meta frame length in words parameter to the value of 2048.

The default value of the Meta frame length in words parameter is 2048.
