Hi, I am using ptp4l application with my custom linux network driver for my hardware which is connected to my server via PCIe.
The connection between my server and other system is direct i.e. no switches in between. -> When I insert my driver, the PCIe card attached to my server gets detected as a NIC card which is visible on ifconfig output. -> I am routing all the packets sent by ptp4l to *queue number 2 *of my HW *.* -> when I run ptp4l, all packets are going and also receiving delay_request packet from the system which my server is connected to, and to which I am responding with delay_response. I am able to achieve sync between my two systems(ptp master and slave). The problem comes when, I run another dpdk based application. The dpdk application routes all the data to *queue number 3* of my same HW. once I run this application, ptp4l stops sending sync follow_up and announce(I am checking in wireshark). What can cause this issue? Why the ptp4l is stopping to send packets. Please help. -Aditya -- Disclaimer:- This footer text is to convey that this email is sent by one of the users of IITH.
