I think you meant virtnet_xdp_handler() actually?
release xdp shinfo then the caller no need to careful the xdp shinfo.

This patch adds the get_vq_state and set_vq_state vDPA callbacks.
In order to get the VQ state, the state needs to be read from the DPU.
In order to allow that, the old messaging mechanism is replaced with a new,
flexible control mechanism.
This mechanism allows to read data from the DPU.
The mec
When suspend is called, the driver sends a suspend command to the DPU
through the control mechanism.

Add more vDPA callbacks.
[s/g]et_vq_state is added in patch 1, including a new control mechanism
to read data from the DPU.
suspend is added in patch 2.

Add VIRTIO_F_NOTIFICATION_DATA support for vDPA transport.
If this feature is negotiated, the driver passes extra data when kicking
a virtqueue.
A device that offers this feature needs to implement the
kick_vq_with_data callback.
kick_vq_with_data receives the vDPA device and data.
