Subject: [PATCH] net/virtio-user: reset used index counter in dev reset
Date: Mon, 5 Aug 2024 10:08:41 +0000 [thread overview]
Message-ID: <20240805100841.276796-1-kshankar@marvell.com> (raw)
When the virtio device is reinitialized during ethdev reconfiguration,
all the virtio rings are recreated and repopulated on the device.
Accordingly, reset the used index counter value back to zero.
