Commit Message

Petr Vorel April 3, 2018, 3:47 p.m. UTC 
The new name states that library supports new API.

This is temporary solution, after migrating all tests to new SHELL API
the compatibility layer and old SHELL API support should be removed.

Add TST_USE_LEGACY_API=1 to all scripts using tst_net.sh (including
testscripts/network.sh).

Filter out TST_IPV6 variable in tst_test.sh.

Could we rename it to tst_net_usage() or similar (for parse_arg()
as well) since it is a library, and use the indent with echo, that
way it would be more readable.

Otherwise the patch looks good!
