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: dev@dpdk.org
Reporter: stephen@networkplumber.org
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.
