Here is what I want to have, in accordance with the KISS principle:

config PTP_1588_CLOCK
	bool "PTP clock support"
	select NET
	select POSIX_TIMERS
	select PPS
	select NET_PTP_CLASSIFY

# driver variant 1:

config ACME_MAC
	select PTP_1588_CLOCK

# driver variant 2:

config ACME_MAC

config ACME_MAC_PTP
	depends on ACME_MAC
	select PTP_1588_CLOCK

Hm?	

Thanks,
Richard
