Subject: [PATCH linux-next v4 6/8] vdpa/mlx5: Fix clearing of VIRTIO_NET_F_MAC feature bit
Date: Thu, 21 Oct 2021 19:35:07 +0300 [thread overview]
Message-ID: <20211021163509.6978-7-parav@nvidia.com> (raw)
In-Reply-To: <20211021163509.6978-1-parav@nvidia.com>
Cited patch in the fixes tag clears the features bit during reset.
mlx5 vdpa device feature bits are static decided by device capabilities.
Clearing features bit cleared the VIRTIO_NET_F_MAC. Due to this MAC address
provided by the device is not honored.
Fix it by not clearing the static feature bits during reset.
Fixes: 0686082dbf7a ("vdpa: Add reset callback in vdpa_config_ops")
