Our network driver support ioctl calls from applications for register reads/writes. I am wondering can ioctl calls be supported from domU to dom0? i.e call flow will be

application invokes ioctl ---> netfront ioctl ----->via xenbus ------> netback ioctl ------> to actual driver in dom0

with the return path in similar fashion.


I'm wondering precisely what register in netback you wish to access?
