53  * Description: During port initialization, the SRIO port performs
58  * the configured port width.
59  * An SRIO port configured as a 4x port may see one of these scenarios:
65  * An SRIO port configured as a 1x port may fail to complete port
67  * Impact: SRIO port may downtrain to 1x, or may fail to complete
68  * link initialization. Once a port completes link initialization
