OK, because this is a 53125S, it should support Broadcom tags correctly,
not clear yet what is happening. Just to make sure, you are using
arch/arm/boot/dts/sun7i-a20-lamobo-r1.dts as the DTS for this platform,
right?
If so, can you provide the ethtool -k eth0 output and/or see if
disabling HW VLAN tag support for eth0 helps in any way?
