Subject: [PATCH v3 net-next 12/12] net: remove obsolete comments about ndo_get_stats64 context from eth drivers
Date: Thu, 7 Jan 2021 11:49:51 +0200 [thread overview]
Message-ID: <20210107094951.1772183-13-olteanv@gmail.com> (raw)
In-Reply-To: <20210107094951.1772183-1-olteanv@gmail.com>
From: Vladimir Oltean <vladimir.oltean@nxp.com>
Now that we have a good summary in Documentation/networking/netdevices.rst,
these comments serve no purpose and are actually distracting/confusing.
Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com>
