Subject: [PATCH net v2] octeontx2-pf: Fix ethtool timestamping capabilities for SDP representors
Date: Tue, 1 Sep 2026 17:18:07 +0530 [thread overview]
Message-ID: <20260901114808.1701352-1-nshettyj@marvell.com> (raw)
From: Roy Franz <rfranz@marvell.com>
SDP representors do not support hardware timestamping. The current
implementation of otx2_get_ts_info incorrectly advertises hardware
timestamping capabilities and a PHC index to userspace for these
interfaces.
Fix this by checking if the device is an SDP representor and returning
the default software timestamping capabilities instead.
Fixes: 2f7f33a09516 ("octeontx2-pf: Add representors for sdp MAC")

v2:
- Disable PTP initialization for SDP representors to cover both
ethtool capabilities and hwtstamp ioctl handling.
