The above is partly garbage.  Please apply 7b02a5e (fix misleading pr_err on
poll timeout) to your sources.

That merely means that message could not be sent due to the missing time
stamping capability.

It's the same situation at different place in the code, just the error message
is different.  Perhaps more intuitive messages are worth inventing.

As to my understanding also the receiving needs time stamping in the driver.

Please update to the latest linuxptp development version before proceeding with
your testing.
