Hi Anshu,
No it's the value of an internal Clock. The frequency and the base are both unknown.
We have a patch that works (but must be reworked before submission to dev) that allows to query the current device clock value. Then from there you can derive the base and the frequency. I can send it to you if you wish.
Tom

Objet : [dpdk-users] MLX5 Rx HW Timestamp units
Anyone know the units of Rx HW timestamps MLX5 provides?
I assumed nanoseconds but tests i have run don't match the nanosecond units.
Thanks,
-Anshu
