[PATCH 4.19 33/77] r8169: work around power-saving bug on some chip versions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Heiner Kallweit <hkallweit1@xxxxxxxxx>

[ Upstream commit e80bd76fbf563cc7ed8c9e9f3bbcdf59b0897f69 ]

A user reported failing network with RTL8168dp (a quite rare chip
version). Realtek confirmed that few chip versions suffer from a PLL
power-down hw bug.
