I have two xiaomi wifi 3g routers. I installed openwrt 19.07 on both. The routers have different configurations, the first with wifi disabled and the second with wifi and wan, but both have the same switch issues.
Example:
#swconfig dev mt7530 show
Global attributes:
enable_vlan: 1
mib: Switch MIB counters
