# TEST_DIR is set by Makefile, when we add a rule to Makefile for odp_l2fwd_run
# we can use TEST_DIR the same way odp_pktio_run uses it now.
# If TEST_DIR is not set it means we are not running with make, and in this case
# there are two situations:
# 1. user build ODP in the same dir as the source (most likely)
#    here the user can simply call odp_l2fwd_run
# 2. user may have built ODP in a separate build dir (like bitbake usually does)
#    here the user has to do something like $ODP/test/performance/odp_l2fwd_run
#
# In both situations the script assumes that the user is in the directory where
# odp_l2fwd exists. If that's not true, then the user has to specify the path
# to it and run:
# TEST_DIR=$builddir $ODP/test/performance/odp_l2fwd_run

# directory where test binaries have been built
TEST_DIR="${TEST_DIR:-$PWD}"
# directory where test sources are, including scripts
TEST_SRC_DIR=$(dirname $0)

PATH=$TEST_DIR:$TEST_DIR/../../example/generator:$PATH
