For IPQ-PPE "Vlan table" is "no". Does it not support vlans at all, or work in progress?
The first column says "Features in Switch menu" which almost certainly means that hardware has support for lots of features. But right now it's only possible to configure them via mentioned menu. The rest of columns indicate particular features, which may be offloaded to HW from bridge configuration. As development continues, it is realistically to expect to see more green fields for IPQ-PPE. But right now, if you create a bridge like this
/interface/bridge/add name=bridge vlan-filtering=yes
this automatically means that all bridge traffic will be handled by CPU (and not by IPQ chip).
