+
+Now that we have b9c7ac4fe22c ("r8169: disable ALDPS per default for
+RTL8125"), the first attempt to fix the issue shouldn't be needed
+any longer. So let's effectively revert 621735f59064 ("r8169: fix
+rare issue with broken rx after link-down on RTL8125") and see
+whether anybody complains.

+Subject: [PATCH] r8169: enable SG/TSO on selected chip versions per default
+
+Due to problem reports in the past SG and TSO/TSO6 are disabled per
+default. It's not fully clear which chip versions are affected, so we
+may impact also users of unaffected chip versions, unless they know
+how to use ethtool for enabling SG/TSO/TSO6.
+Vendor drivers r8168/r8125 enable SG/TSO/TSO6 for selected chip
+versions per default, I'd interpret this as confirmation that these
+chip versions are unaffected. So let's do the same here.

+Subject: [PATCH] r8169: don't take RTNL lock in rtl_task()
+
+There's not really a benefit here in taking the RTNL lock. The task
+handler does exception handling only, so we're in trouble anyway when
+we come here, and there's no need to protect against e.g. a parallel
+ethtool call.
+A benefit of removing the RTNL lock here is that we now can
+synchronously cancel the workqueue from a context holding the RTNL mutex.

+Subject: [PATCH] r8169: avoid duplicated messages if loading firmware fails
+ and switch to warn level
+
+In case of a problem with firmware loading we inform at the driver level,
+in addition the firmware load code itself issues warnings. Therefore
+switch to firmware_request_nowarn() to avoid duplicated error messages.
+In addition switch to warn level because the firmware is optional and
+typically just fixes compatibility issues.

+Subject: [PATCH] r8169: enable EEE at 2.5G per default on RTL8125B
+
+Register a6d/12 is shadowing register MDIO_AN_EEE_ADV2. So this line
+disables advertisement of EEE at 2.5G. Latest vendor driver r8125
+doesn't do this (any longer?), so this mode seems to be safe.
+EEE saves quite some energy, therefore enable this mode per default.

+This aligns some parameters with vendor driver r8125/r8126 to avoid
+compatibility issues. Note that for RTL8125B there's no functional
+change, just the open-coded version of the function is replaced.
