+Subject: [PATCH] r8169: add support for LED's on RTL8168/RTL8101
This adds support for the LED's on most chip versions. Excluded are
the old non-PCIe versions and RTL8125. RTL8125 has a different LED

+Subject: [PATCH] r8169: fix building with CONFIG_LEDS_CLASS=m
+
+When r8169 is built-in but LED support is a loadable module, the new
+code to drive the LED causes a link failure:
+
+ld: drivers/net/ethernet/realtek/r8169_leds.o: in function `rtl8168_init_leds':
+r8169_leds.c:(.text+0x36c): undefined reference to `devm_led_classdev_register_ext'
+
+LED support is an optional feature, so fix this issue by adding a Kconfig
+symbol R8169_LEDS that is guaranteed to be false if r8169 is built-in
+and LED core support is a module. As a positive side effect of this change
+r8169_leds.o no longer is built under this configuration.
+
+Fixes: 18764b883e15 ("r8169: add support for LED's on RTL8168/RTL8101")

+Subject: [PATCH] r8169: improve checking for valid LED modes
+
+After 3a2746320403 ("leds: trigger: netdev: Display only supported link
+speed attribute") the check for valid link modes can be simplified.
+In addition factor it out, so that it can be re-used by the upcoming
+LED support for RTL8125.

+Content-Transfer-Encoding: 8bit
+
+A user reported an unknown chip version. According to the r8168 vendor
+driver it's called RTL8168M, but handling is identical to RTL8168H.
+So let's simply treat it as RTL8168H.

+Subject: [PATCH] r8169: fix LED-related deadlock on module removal
+
+Binding devm_led_classdev_register() to the netdev is problematic
+because on module removal we get a RTNL-related deadlock. Fix this
+by avoiding the device-managed LED functions.
+
+Note: We can safely call led_classdev_unregister() for a LED even
+if registering it failed, because led_classdev_unregister() detects
+this and is a no-op in this case.
+
+Fixes: 18764b883e15 ("r8169: add support for LED's on RTL8168/RTL8101")
