+/**
+ * Driver for software switch emulation of the OFDPA 3.0 pipeline.
+ * The software switch is the CPqD OF 1.3 switch. Unfortunately the CPqD 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 required. As a result this driver works only
+ * on incoming untagged packets.
