However the accuracy of clock offset adjustment is * not guaranted as of now. Also the clock rate adjustment and signalling * frames are not implemented. Also it may not be implementing all aspects of * PTPv2 strictly as per specs. Since it is based on AVB driver (which is * 802.1as based), some aspects of 802.1as which are not there in IEEE1588 * may be there in the protocol implementation inadvertently. The sync frame * interval, announce frame interval and PDelayReq frame intervals are * hard-coded. * * 
* MODIFICATION HISTORY:
*
* Ver   Who  Date     Changes
* ----- ---- -------- -----------------------------------------------
* 1.00a asa  09/16/11 First release based on AVB driver
* 1.01a asa  03/03/12 New hashdefines are added and new function prototypes
* 					  are added.
