And to make it possible for PTP to be configured out, the select statement

default Kconfig value for the PTP subsystem.

With this patch applied, the user is free to set a NIC driver as built
in and PTP_1588_CLOCK as a module, right? If so, that would lead to
non-functional PTP without any warning due to the use of IS_REACHABLE.
That doesn't sound right. Could easily cause hours of headache to
someone.

Or is this handled somehow?

Thanks,
