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. Fixes: 07df5bd874f0 ("r8169: power down chip in probe") Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> --- Note that since the original change source file r8169.c was renamed to r8169_main.c. Also the name of the affected functions has changed from r8168_pll_power_down/up to rtl_pll_power_down/up. --- drivers/net/ethernet/realtek/r8169_main.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-)
