v9:
* Fix a typo in a description.
* In the unit test, make chain length a #define and add a few
RTE_BUILD_BUG_ON().
* The unit test prints when allocating the mbuf pools for the bulk tests.
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.
