In my design, I have to insert some payload in the PAYLOAD of ATM AAL5 CPCS PDU,so I will have to modify the length field and the PAD field of CPCS PDU tailer.
But I have to recalculate the number of the PADding. So I want to know how to add pad ?
If Anybody have experience with Ethernet MAC PAD or ATM pad, please help me!!!!!
