  The rte_eth_dev_close() function now handles freeing resources for
devices (e.g., mac_addrs).  There is no change in behaviour for AVP
devices since they do not currently free their dynamic memory; which was
a bug.  To conform with the new close() behaviour we are asserting the
RTE_ETH_DEV_CLOSE_REMOVE flag so that rte_eth_dev_close() releases
all device related dynamic memory.

+1 to patch.
But Rx/Tx queues are not freed by 'rte_eth_dev_close()', they are still need to
be freed by the driver.
Since you started this, can you please extend the patch to clean them as well?
