Sorry but I do not remember your suggestion on first moving the driver 
out of staging.

Anyhow, I submitted against staging because in an earlier discussion[1] 
it was suggested to first add Rx/Tx capabilities before moving it:

"Ah. Does this also mean it cannot receive?

That makes some of this code pointless and untested.

I'm not sure we would be willing to move this out of staging until it
can transmit and receive."


I'm not sure how I should proceed here.

Thanks,
Ioana
