[LTP] [PATCH v4 2/2] net/route: Add netlink based route change gw/dest tests
Petr Vorel
pvorel@suse.cz
Tue Apr 14 17:24:12 CEST 2020
* use libmnl and new C API
* reuse code in tst_net.h (added in previous commit)
* add shell wrappers (set environment with tst_net.sh instead of using
deprecated helpers in testcases/network/stress/ns-tools/)
Travis:
* add libmnl libraries to most of travis jobs
Cleanup:
* cleanup test description
* other cleanup
