[LTP] [RFC PATCH v7 08/11] network/stress: Fix and cleanup route IPv4 tests

Petr Vorel
2017-07-21T04:04:04Z

* Fix test for netns based testing (route4-change-if requires to have
manually set another pair of interfaces).
* Remove rsh dependency.
* Create shell library route4-lib.sh (route IPv4 specific) to reduce
duplicity in tests. Library uses test_stress_net.sh (and therefore test_net.sh).
* Stop using TST_COUNT, simplify TCID
* Cleanup code, fix typos, update doc.
