Hello James, and others

I'm rather new on this ML, and tested (performance) this drivers on
-Xen 3.2.1 (out of the box opensuse 11.0)
-Xen enterpise 3.1
and on both domU OS windows server 2003R3

tested performance with iperf RX and TX.
on both xen platforms i'd have to had to disable "Large Send offload", if not i didn't came above 1Mbit/s with TX.

performance results with a test machine in same subnet, but beeing another physical machine:
Xen 3.2.1 (opensuse)
 RX: 0.0-60.0 sec  6.32 GBytes    905 Mbits/sec
 TX:                              314 Mbits/sec

Xen enterprise 3.2
 RX: 0.0-60.0 sec  3.46 GBytes    496 Mbits/sec
 TX: 0.0-60.0 sec    681 MBytes  95.2 Mbits/sec

for comparison on Xen enterprice with deleverd (commercial) PV driver:
 RX  0.0-60.0 sec  6.31 GBytes    904 Mbits/sec
 TX: 0.0-59.9 sec  2.78 GBytes    399 Mbits/sec

I've just uploaded 0.9.11-pre7. save/restore should be working for 32
bits on both SMP and UP, and maybe for 64 bits although it's not tested.
If someone could test migration it would be much appreciated.

The installer seems to not install the drivers under 64 bit
environment... but they can then be installed manually. Not sure
why at
this point.
