Subject: Q on ioctl support in netfront/netback

Hello!!!

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.

Looked at the existing netfront and netback drivers and with my
understanding it seems it is not possible. I looked at scsifront and
scsiback, assuming storage drivers should be supporting ioctls, didn't see
anything related to it. Wanted to know what's the mechanism to support
ioctls. Inputs appreciated.

Thanks
-RK
