Subject: ethdev: avoid error on PCI unplug of closed port
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ca5ba1b6972f381d410f9e53b650ba179e776225;p=dpdk.git

ethdev: avoid error on PCI unplug of closed port

If PCI Ethernet device driver removes it on close
(RTE_ETH_DEV_CLOSE_REMOVE) and later PCI device itself is unplugged,
it should not fail because of Ethernet device is already removed.

Fixes: 23ea57a2a0ce ("ethdev: complete closing of port")
