[PATCH v2 net 5/5] net: mscc: ocelot: correctly report the timestamping RX filters in ethtool
From: Vladimir Oltean <vladimir.oltean@nxp.com>
Date: 2021-11-26 17:33:06
Subsystem:
networking drivers, ocelot ethernet switch driver, the rest · Maintainers:
Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Vladimir Oltean, Linus Torvalds
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.
Fixes: 4e3b0468e6d7 ("net: mscc: PTP Hardware Clock (PHC) support")
