From aee686ea17290271d62308b0f559c46e33f6364b Mon Sep 17 00:00:00 2001 From: John McNamara Date: Thu, 2 Jul 2015 16:16:28 +0100 Subject: [PATCH] ethdev: add ieee1588 timestamping Add ethdev API to enable and read IEEE1588/802.1AS PTP timestamps from devices that support it. The following functions are added: rte_eth_timesync_enable() rte_eth_timesync_disable() rte_eth_timesync_read_rx_timestamp() rte_eth_timesync_read_tx_timestamp() Signed-off-by: John McNamara Acked-by: Wenzhuo Lu [Thomas: merged with new macro VALID_PORTID_OR_ERR_RET] --- lib/librte_ether/rte_ethdev.c | 51 ++++++++++++++- lib/librte_ether/rte_ethdev.h | 90 +++++++++++++++++++++++++- lib/librte_ether/rte_ether_version.map | 4 ++ 3 files changed, 143 insertions(+), 2 deletions(-) diff --git a/lib/librte_ether/rte_ethdev.c b/lib/librte_ether/rte_ethdev.c index 44d41b8398..b79e5f7987 100644 --- a/lib/librte_ether/rte_ethdev.c +++ b/lib/librte_ether/rte_ethdev.c @@ -1,7 +1,7 @@ /*- * BSD LICENSE * - * Copyright(c) 2010-2014 Intel Corporation.
