When i am trying to setup many vlan interfacces i have whis dmesg message:

 

rk_gmac-dwmac fe1c0000.ethernet eth0: MAC_VLAN_Tag_Filter full (size: 4)

 

interface info:

 

ethtool -i eth0
driver: st_gmac
version: Jan_2016
firmware-version: 
expansion-rom-version: 
bus-info: 
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

 

I need about 20-30 vlan interfaces

I don’t suppose you ever found a workaround for this? Do we know if this is a driver or hardware issue?

I ran into the same issue. Trying to get PiMox setup on some OrangePi's and found that the OrangePi 5 only supports 4 vlans.

I believe I got a workaround working however. Executing CLI commands (haven't had time to test with /etc/network/interfaces or netplan) for 5 bridges (plus br0). My thought
process was to build separate vlans on the bridge and not vlan interfaces off of eth0. I'm sure this can be improved upon.

#Build bridges
ip link add name br0 address aa:ab:c0:26:f7:f0 up type bridge vlan_filtering 0 vlan_default_pvid 0
ip link add name br1 address aa:ab:c0:26:f7:01 up type bridge vlan_filtering 0 vlan_default_pvid 0
ip link add name br2 address aa:ab:c0:26:f7:02 up type bridge vlan_filtering 0 vlan_default_pvid 0
ip link add name br3 address aa:ab:c0:26:f7:03 up type bridge vlan_filtering 0 vlan_default_pvid 0
ip link add name br4 address aa:ab:c0:26:f7:04 up type bridge vlan_filtering 0 vlan_default_pvid 0
ip link add name br5 address aa:ab:c0:26:f7:05 up type bridge vlan_filtering 0 vlan_default_pvid 0

#Set uplink for br0
ip link set dev eth0 up master br0

# Add vlan to bridges

# Create sub-interfaces for each vlan and assign IP for bridges.
