After a couple of bugfixes, the current mirage-net/direct network stack is working again. I've tested mirage-www successfully on both unix-direct and xen backends.

FYI the bugfixes were:

* pre-zeroing the netfront shared ring

* fixing the IPv4 header calculation so that it includes the TCP header length (oops!)

Cheers,

Dave
