Subject: [PATCH 2/2] common/cnxk: fix VF data offset
Date: Thu, 3 Mar 2022 12:30:42 +0530 [thread overview]
Message-ID: <20220303070042.29075-2-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20220303070042.29075-1-ndabilpuram@marvell.com>
From: Harman Kalra <hkalra@marvell.com>
Data offset should be adjusted for VF to skip extra 8 bytes of timestamp,
if its PF has PTP enabled.
Fixes: c443e0d326e1 ("common/cnxk: support NIX PTP")
