Subject: [dpdk-stable] [PATCH v4 1/7] ethdev: fix port data reset timing
Date: Sat, 20 Jan 2018 21:24:22 +0000 [thread overview]
Message-ID: <1516483468-9048-2-git-send-email-matan@mellanox.com> (raw)
In-Reply-To: <1516483468-9048-1-git-send-email-matan@mellanox.com>
rte_eth_dev_data structure is allocated per ethdev port and can be
used to get a data of the port internally.
rte_eth_dev_attach_secondary tries to find the port identifier using
rte_eth_dev_data name field comparison and may get an identifier of
invalid port in case of this port was released by the primary process
because the port release API doesn't reset the port data.
So, it will be better to reset the port data in release time instead of
allocation time.
Move the port data reset to the port release API.
Fixes: d948f596fee2 ("ethdev: fix port data mismatched in multiple process model")
