Subject: [dpdk-stable] [ PATCH 17.11 1/2] ethdev: clear ethdev data upon detach
Date: Fri, 1 Mar 2019 11:53:22 +0000 [thread overview]
Message-ID: <20190301115323.32420-1-reshma.pattan@intel.com> (raw)
When port is detached its relevant rte_eth_dev_data[port_id]
has to be zeroed, otherwise the next port creations
could get wrong port_id.
Fixes: 92d94d3744 ("ethdev: attach or detach port")
