            Bug ID: 1839
           Summary: af_packet: receive timestamp clock information missing
           Product: DPDK
           Version: 25.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: ethdev
          Assignee: [email protected]
          Reporter: [email protected]

Target Milestone: ---

The af_packet driver optionally provides receive timestamp information, but it is missing the device operation to tell the application what the units of that timestamp is i.e dev->dev_ops->read_clock.

The read_clock routine should return monotonic clock converted to nanoseconds; since that is what the kernel is using internally.
