Filter-based forwarding (FBF) support on L3 sub-interfaces

• FBF on AE and non-AE interfaces 
• FBF on VXLAN-enabled L3 sub-interfaces 
• FBF on IRB interfaces 

If a filter has terms with routing-instance action, only the terms with routing-instance actions will be processed at a higher priority compared to other terms in the filter. Suppose that the filter has term1 without routing-instance action and term2 with routing-instance action: If a packet matches both term1 and term2, then term2 will take a higher priority compared to term1. Therefore, the actions of term2 will be applied.
