+Subject: [PATCH] r8169: fix broken Wake-on-LAN from S5 (poweroff)
+
+It was reported that WoL from S5 is broken (WoL from S3 works) and the
+analysis showed that during system shutdown the network interface was
+brought down already when the actual kernel shutdown started.
+Therefore netif_running() returned false and as a consequence the PHY
+was suspended. Obviously WoL wasn't working then.
+To fix this the original patch needs to be effectively reverted.
+A side effect is that when normally bringing down the interface and
+WoL is enabled the PHY will remain powered on (like it was before the
+original patch).
+
+Fixes: fe87bef01f9b ("r8169: don't check WoL when powering down PHY and interface is down")
