[LTP] [PATCH v5 3/3] network/stress/icmp: add icmp-uni-basic to implement all icmp basic stress test

Hangbin Liu haliu@redhat.com
Wed Apr 13 05:20:25 CEST 2016


Add icmp-uni-basic to implement the test case and define each test case in
"runtest/" and use parameters. Also use ip xfrm instead of setkey for ipsec
testing.
