Subject: [PATCH AUTOSEL 4.14 11/21] net: ena: add missing ethtool TX timestamping indication
Date: Sat, 22 Feb 2020 21:24:01 -0500 [thread overview]
Message-ID: <20200223022411.2159-11-sashal@kernel.org> (raw)
In-Reply-To: <20200223022411.2159-1-sashal@kernel.org>
From: Arthur Kiyanovski <akiyano@amazon.com>
[ Upstream commit cf6d17fde93bdda23c9b02dd5906a12bf8c55209 ]
Current implementation of the driver calls skb_tx_timestamp()to add a
software tx timestamp to the skb, however the software-transmit capability
is not reported in ethtool -T.
This commit updates the ethtool structure to report the software-transmit
capability in ethtool -T using the standard ethtool_op_get_ts_info().
This function reports all software timestamping capabilities (tx and rx),
as well as setting phc_index = -1. phc_index is the index of the PTP
hardware clock device that will be used for hardware timestamps. Since we
don't have such a device in ENA, using the default -1 value is the correct
setting.
Fixes: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
