For applications requiring different values of this parameter – it is more convenient to set the max value via an rte API - rather than changing the dpdk source code per application. In many organizations, the possibility to compile a private DPDK library for a particular application does not exist at all. With this option there is no need to recompile DPDK and it allows using an in-box packaged DPDK. An example usage for updating the RTE_MAX_MEMZONE would be of an application that uses the DPDK mempool library which is based on DPDK memzone library. The application may need to create a number of steering tables, each of which will require its own mempool allocation. This commit is not about how to optimize the application usage of mempool nor about how to improve the mempool implementation based on memzone. It is about how to make the max memzone definition - run-time customized. This commit adds an API which must be called before rte_eal_init(): rte_memzone_max_set(int max). If not called, the default memzone (RTE_MAX_MEMZONE) is used. There is also an API to query the effective max memzone: rte_memzone_max_get().
