196. Unit Tests: Ring Pmd

This is the test plan for the Intel® DPDK Ring poll mode driver feature.

This section explains how to run the unit tests for ring pmd. The test can be launched independently using the command line interface. This test is implemented as a linuxapp environment application and config RTE_LIBRTE_PMD_RING should be modified to ‘Y’.

The complete test suite is launched automatically using a python-expect script (launched using make test) that sends commands to the application and checks the results. A test report is displayed on stdout.

Ring pmd unit test required two pair of virtual ethernet devices and one virtual ethernet devices with full rx&tx functions.

The steps to run the unit test manually are as follow:

# make -C ./app/test/
# ./app/test/test -n 1 -c ffff --vdev='net_ring0'
    --vdev='net_ring1'
RTE>> ring_pmd_autotest

The final output of the test has to be “Test OK”
