ADF7242 Operation

Hi,
This is regarding the ADF7242:
1. What does the firmware do when RC_CSMACA command is given to it?
2. Does the firmware pass the 11 byte ack-frames to the Linux driver? Can we get it with RX_PKT_RCVD interrupt on Linux driver?
3. Is there a way to check the number of Transmit retries before a successful transmit of data packet?
