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

 



From: Heiner Kallweit <hkallweit1@xxxxxxxxx>

[ Upstream commit 87e26448dbda4523b73a894d96f0f788506d3795 ]

Vendor drivers r8125/r8126 indicate that this quirk isn't needed
any longer for RTL8126A. Mimic this in r8169.
