[LTP] [RFC PATCH v2 1/3] test_net.sh: Support both old and new shell APIs

Petr Vorel pvorel@suse.cz
Fri Mar 30 01:31:32 CEST 2018


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

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.
