Subject: [PATCH 2/2] event/cnxk: add callback handler to read ptp timestamp
Date: Thu, 24 Feb 2022 13:32:17 +0530 [thread overview]
Message-ID: <20220224080217.2895297-2-rkudurumalla@marvell.com> (raw)
In-Reply-To: <20220224080217.2895297-1-rkudurumalla@marvell.com>
timestamp resolution for an incoming and outgoing packets
is different for CN10k and CN9K.Added platform specific
callback to retrieve timestamp in correct format when read by
application
