[PATCH] virtio_net: fix mergeable bufs error handling
On xdp error we try to free head_skb without having
initialized it, that's clearly bogus.

[PATCH net] virtio-net: keep vnet header zeroed after processing XDP
...ong
since XDP may modify the packet data. So let's keep a zeroed vnet
header for not confusing the conversion between vnet header and skb
metadata.
In the future, we should able to detect whether or not the packet was
modified and keep using the vnet header when packet was not touched.

[PATCH net 1/2] virtio-net: disable guest csum during XDP set
We don't disable VIRTIO_NET_F_GUEST_CSUM if XDP was set. This means we
can receive partial csumed packets with metadata kept in the
vnet_hdr. This may have several side effects:
- It could be overridden by header adjustment, thus is might be not
correct after XDP processing.
- There's no way to pass such metadata information through
XDP_REDIRECT to another driver.
- XDP does not

[PATCH net 2/2] virtio-net: fail XDP set if guest csum is negotiated
We don't support partial csumed packet since its metadata will be lost
or incorrect during XDP processing. So fail the XDP set if guest_csum
