SerialLite II Priority Port Latency

Hi Folks. 

 

I'm currently developing a design that uses SerialLiteII and I wish to use the Priority Port (PP).  

 

I am using 4x6.25Gbps lanes so have a 128-bit (16-byte) interface. The packet I want to send on the PP is 32-bytes long (2 clks @ 175MHz). My problem is that I can't find anywhere any information relating to the latency of transmission on the PP. I understand that it is going to be impossible to get an absolute figure because of the different link-layer packets etc but has anyone got any idea about what sort of range of figures i could expect or how to work it out or where to look to get the info ? 

 

Any and all help much appreciated.
