But many drivers's callback can only handle key-value, it will segment fault if handles only-key. so the patchset [1] was introduced. Because the patchset [1] modified too much drivers, therefore: 1) A new API rte_kvargs_process_opt() was introduced, it inherits the function of rte_kvargs_process() which could parse both key-value and only-key. 2) Constraint the rte_kvargs_process() can only parse key-value. This patchset also include one bugfix for kvargs of mvneta driver.
