Seems too aggressive, we do not use up the whole page for the size.

[PATCH net-next 1/2] virtio-net: don't reserve space for vnet header for XDP
We tried to reserve space for vnet header before
xdp.data_hard_start. But this is useless since the packet could be
modified by XDP which may invalidate the information stored in the
header and there's no way for XDP to know the existence of the vnet
header currently.
So let's just not reserve space for vnet header in this case.
