I don't understand this patch at all.
There is no comment in the code, and the commit log is not very explanatory.
You are lucky Ferruh is less strict than me.
I remember I already said I was bored of the lack of explanations in NXP drivers.
[Hemant] We will improve next time.
The patch description says: "> This patch enables the packet timestamping conditionally when Rx
> offload is enabled for timestamp."
It should be improved with - Enable the timestamping by default when IEEE1588 is enabled irrespective of offload flag.
