**                  on this connection. PAN is responsible to release the buffer
**
** Parameters:      handle      - handle for the connection
**                  src         - source BD Addr
**                  dst         - destination BD Addr
**                  protocol    - Network protocol of the Eth packet
**                  p_buf       - pointer to the data buffer
**                  ext         - to indicate whether the data contains any
**                                         extension headers before the payload
