Also print when freeing them. v8: * Add unit test, covering both bulk alloc and bulk free. v7: * Squash multiple modifications into one. v6: * Remove __rte_always_inline from static function. The compiler will inline anyway. v5: * Rename variables from "free" to "pending" for improved readability. * Add prefix __ to rte_pktmbuf_free_seg_via_array(). * Add array size parameter to __rte_pktmbuf_free_seg_via_array(). The compiler will optimize the parameter away anyway. * Add description to __rte_pktmbuf_free_seg_via_array(). * Minor description updates. v4: * Mark as experimental by adding __rte_experimental. * Add function to experimental section of map file. * Fix source code formatting regarding pointer to pointer. * Squash multiple modifications into one. v3: * Bugfix: Handle pakets with multiple segments. * Add inline helper function, mainly for readability. * Fix source code formatting regarding indentation. v2: * Function is not inline. * Optimize to free multible mbufs belonging to the same mempool in bulk. Inspired by ixgbe_tx_free_bufs(), but allowing NULL pointers in the array, just like rte_pktmbuf_free() can take a NULL pointer. * Use unsigned int instead of unsigned. Passes checkpatch, but mismatches the original coding style of the modified files. * Fix a typo in the description headline: mempools is plural.
