Just a stylistic nit-pick: this variable definition section looks
pretty ugly. Those externs should be in a header and in any case
different types of lines should generally not be mixed without at
least a newline between them.

Naming nit: 'struct virtio_net_params' is shorter by 4 chars and just
as expressive.

Isn't 'buf' leaked here?
Patch looks good otherwise.
