Description

current_time

See timestamp structure

gm_priority

See priority_vector structure

ms_offset_ns

Master slave offset in nano seconds Valid when the port role is in slave mode.

is_sync

Returns the gptp is synchronization status. un-synced = 0 synced = 1 - valid when the port role is in slave mode.

link_status

Gives the link status of the gptp enabled port. link down = 0 link up = 1

link_delay_ns

Gives the link delay between the device and the link partner in nano second. Value is valid when the device is - in standard profile - in automotive profile - port role is slave mode

selected_role

Indicates current port role, disabled, master, slave or passive. DISABLED = 0 PASSIVE = 1 (Passive is only available for gptp switch mode) MASTER = 2 SLAVE = 3

as_capable

indicates 802.1AS capability 0 = Not 802.1AS capability 1 = 802.1AS capability

is_syntonized

Indicates if gPTP is syntonized or not. Valid when the port role is in slave mode. 1 = if device is syntonized with grand master 0 = if not
