            Bug ID: 544
           Summary: l3fwd attempts to create too many TX queues
           Product: DPDK
           Version: 20.08
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: examples
          Assignee: [email protected]
          Reporter: [email protected]

Target Milestone: ---

When initializing l3fwd, the number of TX queues will be decided by minimum of either max number of TX queues (set to max number of devices), or number of lcores. This prevents l3fwd from running when the number of lcores/devices exceeds the max number of queues per device. This is easily reproducible with creating a couple of pcap vdevs and attempting to do forwarding on them.
