DPDK unit test TestDpdkMultiThread fails on openMultiQueues assertion #2010
Description
When running the PcapPlusPlus unit test suite, the TestDpdkMultiThread test case fails. The failure is due to an Assert FALSE failure on dev->openMultiQueues(numOfRxQueuesToOpen + 1, 1). This indicates that the function unexpectedly returned true when attempting to open more queues than the device supports, whereas it is expected to return false.
The operating system used is Ubuntu 22.04, and the DPDK version is 21.11.9.
