Subject: [PATCH 7/8] net: mscc: ocelot: correctly report the timestamping RX
filters in ethtool
Git-commit: c49a35eedfef08bffd46b53c25dbf9d6016a86ff
Patch-mainline: v5.16-rc3
References: git-fixes
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")
