Query regarding PTP_1588_CLOCK

From: Valdis Kletnieks

In drivers/net/ethernet/intel/Kconfig, we see this:

config E1000E
tristate "Intel(R) PRO/1000 PCI-Express Gigabit Ethernet support"
depends on PCI && (!SPARC32 || BROKEN)
select CRC32
select PTP_1588_CLOCK
---help---

Is there a reason for the PTP_1588_CLOCK select? That ends up
forcing the PTP and PPS stuff into the kernel as well - and I don't
use any of it.
