+# trex_root_path: trex tar package decompression directory

+# trex_lib_path(optional): trex stateless client libs directory, it is optional.
+#    If it is not set, use a default relative directory.
+# coremask:
+#  1. a list of masks (one core mask per port), sort sequence as 
+#    <port 0 core mask>,<port 1 core mask>
+#     example:  core_mask=0x3,0x5
+#  2. CORE_MASK_PIN
+#     for each dual ports (a group that shares the same cores), the cores will
+#     be divided half pinned for each port.
+#     example:  core_mask=CORE_MASK_PIN
+# num -n: Number of memory channels
+# proc_type --proc-type: Type of this process
+# pci_blocklist --pci-blocklist, -b: Add a PCI device in block list.
+# pci_allowlist --pci-allowlist, -a: Add a PCI device in allow list.
+# file_prefix --file-prefix: Prefix for hugepage filenames
+# socket_memory --socket-mem: Memory to allocate on specific sockets
+# mapping_ports -m: Matrix for mapping ports to logical cores.
+# pcap_port_num -s P:file: The PCAP packet file to stream. P is the port number.
