Port 0 statistic counter wrap around interrupt mask. An Interrupt is generated when a statistic
counter wraps around. Refer to hardware statistic counter for interrupt sources
Port 0 link change mask
Port 0 module detect mask
Reserved
Port 1 statistic counter wrap around interrupt mask. An interrupt is generated when a statistic
counter wraps around. Refer to hardware statistic counter for interrupt sources.
