The tests are registered with their command name by adding a structure to a list. The structure of each test was declared in each test file and passed to the register macro. This rework generate the structure inside the register macro. Signed-off-by: Thomas Monjalon <thomas.monjalon@6wind.com> Reviewed-by: Jan Viktorin <viktorin@rehivetech.com>

/*
|
|
* Per-lcore variables and lcore launch
|
|
* ====================================
|
|
*
|
|
* - Use ``rte_eal_mp_remote_launch()`` to call ``assign_vars()`` on
|
|
* every available lcore. In this function, a per-lcore variable is
|
|
* assigned to the lcore_id.
|
|
*
|
|
* - Use ``rte_eal_mp_remote_launch()`` to call ``display_vars()`` on
|
|
* every available lcore. The function checks that the variable is
|
|
* correctly set, or returns -1.
|
|
*
|
|
* - If at least one per-core variable was not correct, the test function
|
|
* returns -1.
