/**
 * Driver for software switch emulation of the OFDPA pipeline.
 * The software switch is the OVS OF 1.3 switch. Unfortunately the OVS switch
 * does not handle vlan tags and mpls labels simultaneously, which requires us
 * to do some workarounds in the driver. This driver is meant for the use of
 * the cpqd switch when MPLS is not a requirement from the ofdpa pipeline. As a
 * result this driver correctly handles both incoming untagged and vlan-tagged
 * packets.
