| devargs | string |  | Open vSwitch DPDK device arguments. | 
| n-rxq | uint32 | 0 | Open vSwitch DPDK number of rx queues. Defaults to zero which means to leave the parameter in OVS unspecified and effectively configures one queue. | 
| n-rxq-desc | uint32 | 0 | The rx queue size (number of rx descriptors) for DPDK ports. Must be zero or a power of 2 between 1 and 4096, and supported by the hardware. Defaults to zero which means to leave the parameter in OVS unspecified and effectively configures 2048 descriptors. | 
| n-txq-desc | uint32 | 0 | The tx queue size (number of tx descriptors) for DPDK ports. Must be zero or a power of 2 between 1 and 4096, and supported by the hardware. Defaults to zero which means to leave the parameter in OVS unspecified and effectively configures 2048 descriptors. |
