Subject: [PATCH 4.19 16/50] r8169: fix issue with confused RX unit after PHY power-down on RTL8411b
Date: Fri, 26 Jul 2019 17:24:51 +0200 [thread overview]
Message-ID: <20190726152302.226615840@linuxfoundation.org> (raw)
In-Reply-To: <20190726152300.760439618@linuxfoundation.org>
From: Heiner Kallweit <hkallweit1@gmail.com>
[ Upstream commit fe4e8db0392a6c2e795eb89ef5fcd86522e66248 ]
On RTL8411b the RX unit gets confused if the PHY is powered-down.
This was reported in [0] and confirmed by Realtek. Realtek provided
a sequence to fix the RX unit after PHY wakeup.
The issue itself seems to have been there longer, the Fixes tag
refers to where the fix applies properly.
