Bug ID: 1843
Summary: net/nfb: missing read_clock
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 nfb driver has option to provide receive timestamps from hardware.
But there is on option to find out the units.
The standard ethdev operation for that is read_clock
Reading the code it looks like it is done as a split upper 32 bits is seconds
and lower 32 bits is nanoseconds. This doesn't conform to the expectation that
the timestamp is a monotonically increasing value from hardware clock. Not sure
if comment or code is wrong here.
