###Check environment K8S_SRIOV_DP (0 or 1, default 0), K8S_CPU_MANAGER (0 or 1, default 0), XRAN_DIR before running this script

###Parameters:

###$1 - used to specify sriov net devices to run XRAN sample app.
###The input will be different depending on k8s sriov device plugin enabled or not.
###If k8s sriov net device plugin is enabled, container will request integral sriov VF devices ($1) from k8s,
###which is specified in the pod configuration file like - intel.com/intel_sriov_dpdk: "2".
###Then the input of this parameter would be number like 2, or 4.
###Else this parameter $1 will be sriov net devices PCIe address list like "18:02.0 18:02.1"

###$2 - Test case index. Like "mu3_100mhz"

###$3 - "du" or "ru"

###$4 - Instance/wls ID. Like "1", "2", or "3".

###$5 - Used to assign core affinity to different threads of XRAN sample app.
###If this parameter input is "0", k8s CPU Manager is enabled, and this script will get core mapping from the container taskset affinity,
###which is assigned by the CPU Manager.
###Else this parameter input should be taskset core mask assigned by user (in Hex format, but removing 0x in the head), like "0000f0"
