This patch adds the required setting for running linuxptp time-sync. The patch has been tested on both PSE (/dev/ptp0) and PCH TSN(/dev/ptp2) and the results for the time sync looks correct. ############################ PSE TSN #################################### > cat gPTP.conf [global] gmCapable 1 priority1 248 priority2 248 logAnnounceInterval 0 logSyncInterval -3 syncReceiptTimeout 3 neighborPropDelayThresh 800 min_neighbor_prop_delay -20000000 assume_two_step 1 path_trace_enabled 1 follow_up_info 1 transportSpecific 0x1 ptp_dst_mac 01:80:C2:00:00:0E network_transport L2 delay_mechanism P2P ingressLatency 231 egressLatency 147 tx_timestamp_timeout 50 > /usr/local/sbin/ptp4l -v 3.1 ################################# #
