net/nfb: remove resources when dev is closed
Checks
Commit Message
From: Rastislav Cernay <cernay@netcope.com>
The rte_eth_dev_close() function now handles freeing resources for
devices (e.g., mac_addrs). 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 level dynamic memory.

The device private pointer (dev_private) is of type void *, therefore this
cast is unnecessary.
