Hi Stephen,
It seems standard (non-json) vlan stats output has been broken since commit:
0f36267485e3 ("bridge: fix vlan show formatting")
bridge -s vlan show output before commit 0f36267485e3:
port vlan id
br0 1 PVID untagged
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
eth4 1 PVID untagged
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
bridge -s vlan show output after commit 0f36267485e3:
root@debian~/# bridge -s vlan
