For the sake of completeness, the MX95 B0 I have on my desk now prints 
this in SM:

>$ clock.r
...
097: busnetcmix           =  on,  133333333Hz
098: enet                 =  on,  666666666Hz
099: enetphytest200m      =  on,   24000000Hz
100: enetphytest500m      =  on,   24000000Hz
101: enetphytest667m      =  on,   24000000Hz
102: enetref              =  on,  250000000Hz
103: enettimer1           =  on,   24000000Hz

And the cycle time of MDC is 1.8ms , which is some 550 kHz .
