Hardware timestamping for IEEE 1588 (PTP) via UDP not working with default values

Hi,

 

We are currently working on PTP implementation using DPDK with Intel X520-DA2 (82599 Controller). We encountered an issue with default configuration of 82599 controller for UDP port number filter.

 

As stated in datasheets(8.2.3.26.6), register RXMTRL(31:16 bit) is default initialized to value 0x319 (dec: 793), but it should be 0x13F (dec: 319).

 

8.2.3.26.6 Rx Message Type Register Low — RXMTRL (0x05120; RW)

UDPT | 31:16 | 0x319 | UDP port number to time stamp.

 

This post is just informational for anyone looking for this problem.

Also we think this should be stated somewhere in datasheets (or errata) that this value is misconfigured and will not be working with default ptp implementations.

 

Regards,

Artur
