Implementation of PTP in Ettus N320

[Mathis]

Dear Mailing List,
I'm currently working on aprojectabout theprotocol White 
RabbitandPTP.Todothis,IusetheUSRPN320, andI'm able tostartamaster/slave 
architecture andruna complete synchronization between twodevices.Fornow, 
I haveto redirectPTPmessagesoverradioinstead of optical fiber.Sofor the 
firststep, I'mlookingfor the source code thatimplementthePTPprotocol.I 
didn'tfoundanything inside the hardware source code of UHD 
<https://github.com/EttusResearch/uhd>.So I thoughtitwasa 
softwareimplementationofPTP, but I didn't found anydeamonrunning in 
theEttusN320during the synchronization. I also found thewrpc-sw 
<https://github.com/EttusResearch/wrpc-sw>whichincludeas a submodule 
thenewversionPPSiwhich clearly implement PTP but it seems like any of 
those two software are notrunning onmysystem.

Myquestion is:Where is implementedthePTPprotocolfor the synchronization 
for the Ettus N320 betweenMasterand Slave?

Best regards,
Mathis
