i only see 1 network binding...and this is labeled/described with wlan and phy

        # LED is triggered by WLAN activity
      - pattern: "^phy[0-9]+tx$"

which second do you mean?

btw. usb + disk has 3 trigger and "netdev" is already used in some dts, so i thought adding the binding is a good idea

arch/arm/boot/dts/rockchip/rk3128-xpi-3128.dts:107:			 * linux,default-trigger = "netdev";
arch/arm/boot/dts/nxp/imx/imx53-m53menlo.dts:52:			linux,default-trigger = "netdev";
arch/arm/boot/dts/intel/ixp/intel-ixp42x-dlink-dsm-g600.dts:51:			linux,default-trigger = "netdev";
arch/arm/boot/dts/intel/ixp/intel-ixp42x-iomega-nas100d.dts:39:			linux,default-trigger = "netdev";
arch/arm/boot/dts/ti/omap/am5729-beagleboneai.dts:138:			linux,default-trigger = "netdev";
arch/arm/boot/dts/ti/omap/am335x-netcan-plus-1xx.dts:27:			linux,default-trigger = "netdev";
arch/mips/boot/dts/ralink/gardena_smart_gateway_mt7688.dts:107:			linux,default-trigger = "netdev";
arch/mips/boot/dts/ralink/gardena_smart_gateway_mt7688.dts:113:			linux,default-trigger = "netdev";

first one has it as comment that not yet in binding and with not that it needs to be set in userspace
like Daniel stated in the dts patch (does not work for phys)...so i drop this patch and the property
in the dts.
