Hi Richard
"Then you need to allocate a second MAC to act as the DSA management
port.  The management port cannot participate in the PTP."


Do you mean that I can not use eth0 as the DSA management port ,since I need to 
run ptp on it? 
Sorry, I do not understand  a second MAC, what does this mean?

Correct.

&gt; Is there any patch for this to work?

I'm sorry, but that is impossible.

&gt; We could like to get pps&amp;nbsp; supported by eth0, since dsa driver of 
marvel switch we are using does not support pps.

Sorry,
