From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mateusz Palczewski Date: Mon, 23 Nov 2020 13:46:56 +0000 Subject: [Intel-wired-lan] [PATCH net v1] i40e: allow controlling PTP external clock features Message-ID: <20201123134656.14911-1-mateusz.palczewski@intel.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: intel-wired-lan@osuosl.org List-ID: From: Piotr Kwapulinski 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.
