+Task #10 - ICMPv6 stress test on native (1 hour)
+================================================
+### Description
+
+Rapid ICMPv6 echo request/reply exchange from 10 host ping applications
+simultaneously to one native node.
+* Stack configuration: IPv6 (default)
+* Count:                  Infinity
+* Interval:               0ms
+* Payload:                1452B
+* Destination Address:    Link local unicast (fe80::.../64)
+
+### Result
+
+All nodes are still running, reachable, and the packet buffer is empty 10
+seconds after completions (use module `gnrc_pktbuf_cmd`).
+Packet loss is irrelevant in this stress test.
