Description copied from class: Ofdpa2Pipeline

Internal implementation of processVlanIdFilter.

The is_present bit in set_vlan_vid action is required to be 0 in OFDPA i12. Since it is non-OF spec, we need an extension treatment for that. The useVlanExtension must be set to false for OFDPA i12.

NOTE: Separate VLAN filtering rules and assignment rules into different stages in order to guarantee that filtering rules always go first, as required by OFDPA.

Overrides:

processVlanIdFilter in class Ofdpa2Pipeline

Parameters:

portCriterion - port on device for which this filter is programmed

vidCriterion - vlan assigned to port, or NONE for untagged

assignedVlan - assigned vlan-id for untagged packets

applicationId - for application programming this filter

install - indicates whether to add or remove the objective

Returns:

stages of flow rules for port-vlan filters

ethCriterion - dstMac of device for which is filter is programmed

vidCriterion - vlan assigned to port, or NONE for untagged
