[Intel-wired-lan] [PATCH net v1] i40e: allow controlling PTP external clock features

[Mateusz Palczewski]

From: Piotr Kwapulinski <piotr.kwapulinski at intel.com>

Provide information what functions are supported by PTP pins and allow
controlling them.
Implemented in i40e_ptp_verify() and i40e_pps_configure().
Previously it was not possible to control PTP external clock features.
