Subject: [PATCH AUTOSEL 3.18 08/15] sr9800: Check for supported Wake-on-LAN modes
Date: Tue, 16 Oct 2018 00:16:43 -0400 [thread overview]
Message-ID: <20181016041650.135958-8-sashal@kernel.org> (raw)
In-Reply-To: <20181016041650.135958-1-sashal@kernel.org>
From: Florian Fainelli <f.fainelli@gmail.com>
[ Upstream commit c5cb93e994ffb43b7b3b1ff10b9f928f54574a36 ]
The driver currently silently accepts unsupported Wake-on-LAN modes
(other than WAKE_PHY or WAKE_MAGIC) without reporting that to the user,
which is confusing.
Fixes: 19a38d8e0aa3 ("USB2NET : SR9800 : One chip USB2.0 USB2NET SR9800 Device Driver Support")
