[LTP] [PATCH 6/6] net/{stress, virt}: Migrate tests using virt_lib.sh and ipsec_lib.sh

Petr Vorel pvorel@suse.cz
Mon Jun 18 19:37:07 CEST 2018


+ these libraries itself.

It was needed to migrate it all in once, as macsec0{1,2}.sh tests are
using both libraries.

This includes:
* Create setup, getopts and helper function for both libraries.
* Using TST_TEST_DATA and TST_TEST_DATA_IFS in many test cases
(simplify tests and allow to have more TST_CNT to keep readability of
output + required by udp_ipsec.sh and udp_ipsec_vti.sh otherwise it'd
need to use getopts to determine type of udp, as passing parameter to
tst_run is not not recommended to new API).
* Put code into TST_TESTFUNC functions.
* Move anything based on TST_IPV6 to TST_SETUP setup functions (as
TST_IPV6 is not set until setup)

Other changes:
* udp_ipsec{,_vti}.sh: were calling do_test() twice, with parameter.
Now they use correctly TST_CNT and no params.
Order of running tests changed. Before first were run udp tests for all
items in $IPSEC_SIZE_ARRAY, then all udp_lite tests. Now for each item
in $IPSEC_SIZE_ARRAY both udp and udp_lite tests are run.
* gre01.sh: Move back device type setting (changed in 57738337a
"network/gre01: fix device type setting").
