Subject: [PATCH v1 2/3] net/ice: fix PTP clock corruption with TxPP
Date: Mon, 27 Oct 2025 14:28:00 -0400	[thread overview]
Message-ID: <20251027182801.191295-3-soumyadeep.hore@intel.com> (raw)
In-Reply-To: <20251027182801.191295-1-soumyadeep.hore@intel.com>

On enabling TxPP PTP clock was getting corrupted as timesync was enabled
on during setup. Currently timesync will be enabled during start of tx
queue, hence enabling PHC clock to get updated on starting and stopping
of ports.

Fixes: 0b6ff09a1f19 ("net/intel: support Tx packet pacing for E830")
