Thomas Monjalon Sept. 27, 2020, 11:42 p.m. UTC
The function rte_eth_dev_release_port() was resetting partially
the struct rte_eth_dev. The drivers were completing it
with more pointers set to NULL in the close or remove operations.

A full memset is done so most of those assignments become useless.
