From 7b9237a8ef194c5c20c3c4fba2486422ac96b1a8 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 26 Nov 2021 19:28:45 +0200 Subject: [PATCH] net: mscc: ocelot: correctly report the timestamping RX filters in ethtool [ Upstream commit c49a35eedfef08bffd46b53c25dbf9d6016a86ff ] The driver doesn't support RX timestamping for non-PTP packets, but it declares that it does. Restrict the reported RX filters to PTP v2 over L2 and over L4.
