| 22 | * Driver for software switch emulation of the OFDPA pipeline. |
| 23 | * The software switch is the OVS OF 1.3 switch. Unfortunately the OVS switch |
| 24 | * does not handle vlan tags and mpls labels simultaneously, which requires us |
| 25 | * to do some workarounds in the driver. This driver is meant for the use of |
| 26 | * the cpqd switch when MPLS is not a requirement from the ofdpa pipeline. As a |
| 27 | * result this driver correctly handles both incoming untagged and vlan-tagged |
| 28 | * packets. |
