[PATCH 0/2] Allow VIRTIO_F_IN_ORDER negotiation with vhost-vdpa

[Gautam Dawar]

The VIRTIO_F_IN_ORDER feature is implemented by DPDK virtio_net driver
but not by the Linux kernel's virtio_net driver.

However, this feature can't be tested using vhost-vdpa even with HW devices
that implement it as VIRTIO_F_IN_ORDER isn't defined in kernel's
virtio_config.h header file yet and hence is not available in QEMU.

Accordingly, as a first step, a patch for defining VIRTIO_F_IN_ORDER in
kernel (version 5.17-rc4, file: include/uapi/linux/virtio_config.h) has
been published.

This patch series first brings in VIRTIO_F_IN_ORDER's definition from Linux
kernel using the script update-linux-headers.sh.
Next, it adds VIRTIO_F_IN_ORDER to host_features in case the underlying
vdpa device exposes this feature bit in device featues there by making it
available for negotiation with the virtio_net driver.
