+# This issue states that if other ports, in the same card,
+# are in kernel mode, they could impair traffic counting.
+# Can be overridden by --i40e-mixed
+# Values can be:
+# ignore - don't consider the case (default)
+# exit - should the case arise, exit (TRex default behaviour)
+# unbind - unbind kernel bound ports (the former NFVbench behaviour)
+# The 'ignore' option might be OK as soon as the issue has been fixed in the driver.
+# The 'unbind' option should not be used! who knows the current use of other ports?
