Some require multiple cores (but those tests\nshould be modified to 'SKIP' when the correct number of cores\naren't available).\n\nThe unit test results shouldn't be impacted by this change, but it\nallows for a future enhancement to pass flags such as '--no-huge'.\n\nAlso include a fix to a reported issue with running on FreeBSD.\n\nSigned-off-by: Aaron Conole <aconole@redhat.com>\n---\nConflicts with http://patches.dpdk.org/patch/50850/\n\n app/test/meson.build | 24 +++++++++++++++++++++---\n 1 file changed, 21 insertions(+), 3 deletions(-)",
