[PATCH] net: ti: am65-cpsw: Update hw timestamping filter for PTPv1 RX packets
From: vishnu singh <hidden>
Date: 2025-09-17 04:15:14
From: Vishnu Singh <redacted> CPTS module of CPSW supports hardware timestamping of PTPv1 packets.Update the "hwtstamp_rx_filters" of CPSW driver to enable timestamping of received PTPv1 packets. Also update the advertised capability to include PTPv1.
