usbatm question

[matthieu castet]

Hi,

I have questions about usbatm api.


usbatm use intfdata for storing its private data, so the driver 
shouldn't use it.
But how could the driver recover its private data for example for an ioctl?
Could the driver assume that there is always usbatm private data and use 
usbatm->driver_data ?

For the atm statistic (rate and state), is it safe to access it any time ?
Some modem could start their stats loop in heavy init, because they need 
to know the state of the modem in order to send it the correct part of 
the firmware. Is it need to check if atm_start finished before updating 
atm stats ?
