From: Maxime Coquelin Date: Mon, 1 Feb 2021 20:31:38 +0000 (+0100) Subject: net/virtio: fix PCI ops assignment X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b93c3530c1fbcb8929dd0ceed1dfea0f7d470973;p=dpdk.git net/virtio: fix PCI ops assignment VIRTIO_OPS() macro relies on the port ID stored in the virtio_hw struct. Issue is that it is used before being assigned at init time. It results in all devices setting ops on port ID 0, causing crash later when calling ops for port IDs other than 0. This patch ensures port ID assignment is done at early primary process probe time, before it is being used.
