    devargs
    string
| Open vSwitch DPDK device arguments.
    lsc-interrupt
    int32
    -1
| Configures the Link State Change (LSC) detection mode for the OVS DPDK interface. When set to -1 (ignore), NetworkManager doesn't change the default value configured by Open vSwitch. 1 (enabled) enables interrupts. 0 (disabled) disables interrupts, thus setting the interface in poll mode.
    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.
