           Summary: DMA Perf test unable to parse multiple DMA devices
                    from configuration file
           Product: DPDK
           Version: 23.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Description: running dpdk-perf-test for DMA on Intel (Intel(R) Xeon(R) Platinum
8471N) for multiple devices and queues combination.

Sample Config File: `[DPDK root folder]/app/test-dma-perf/config.ini`
Current Value: `lcore_dma=lcore10 at 0000:00:04.2, lcore11 at 0000:00:04.3`
Modified value:
`lcore_dma=lcore10 at 0000:00:04.2-q0,lcore12 at 0000:00:04.2-q1,lcore13 at 0000:00:04.2-q2,lcore14 at 0000:00:04.2-q3,lcore15 at 0000:00:04.2-q4,lcore16 at 0000:00:04.2-q5,lcore17 at 0000:00:04.2-q6,lcore18 at 0000:00:04.2-q7,lcore19 at 0000:00:04.4-q0,lcore20 at 0000:00:04.4-q1,lcore21 at 0000:00:04.4-q2,lcore22 at 0000:00:04.4-q3,lcore23 at 0000:00:04.4-q4,lcore24 at 0000:00:04.4-q5,lcore25 at 0000:00:04.4-q6,lcore26 at 0000:00:04.4-q7`


Expected behavior:
All the devices are initialized and DMA Perf test run on 16 dma devices.
Observed behavior:
dma Perf test runs only on first 7 Devices.
