Subject: [dpdk-dev] [PATCH] net/thunderx: fix nicvf cleanup on detaching PCI dev
Date: Mon, 5 Aug 2019 13:30:44 +0530	[thread overview]
Message-ID: <1564992051-11150-1-git-send-email-agupta3@marvell.com> (raw)

From: Amit Gupta <agupta3@marvell.com>

There was a bug while doing PCI detach because of that
app gets seg fault as eth_dev is released without
stopping/cleaning up mapped nicvf.

Fixed this bug by adding nicvf cleanup stupport on PCI detach.

Fixes: fdf91e0f2fac ("drivers/net: do not use ethdev driver")
