Tested with DSA driver and Kernel 4.14 Note: "make sure that port 0 of the internal switch is not accidentally configured back to untagged since that would cause problem when terminating the VLAN tag on the SW side." - Florian Fainelli [1] So, I had to run following bridge command: bridge vlan add vid 1 dev extsw pvid tagged Changes in v2: - Properly define mdio mux, internal mdio, external mdio, mii bus - Now we define usb3 phy as a mdio node connected to internal mdio Thanks to work done by Rafał Miłecki on the usb3 phy mdio driver - Define external SW as a mdio-mii node connected to external mdio [1] https://www.spinics.net/lists/arm-kernel/msg590992.html Signed-off-by: Vivek Unune <npcomplet...@gmail.com> --- arch/arm/boot/dts/bcm47094-linksys-panamera.dts | 239 +++++++++++++++++++++++- arch/arm/boot/dts/bcm47094.dtsi | 6 +- arch/arm/boot/dts/bcm5301x.dtsi | 55 +++++- 3 files changed, 288 insertions(+), 12 deletions(-) diff --git a/arch/arm/boot/dts/bcm47094-linksys-panamera.dts b/arch/arm/boot/dts/bcm47094-linksys-panamera.dts index b6750f7..5f53207 100644 --- a/arch/arm/boot/dts/bcm47094-linksys-panamera.dts +++ b/arch/arm/boot/dts/bcm47094-linksys-panamera.dts @@ -7,7 +7,7 @@ /dts-v1/;
