func (*Path) PrependAsn 

func (path *Path) PrependAsn(asn uint32, repeat uint8, confed bool)

PrependAsn prepends AS number. This function updates the AS_PATH attribute as follows. (If the peer is in the confederation member AS, 

replace AS_SEQUENCE in the following sentence with AS_CONFED_SEQUENCE.)
1) if the first path segment of the AS_PATH is of type
   AS_SEQUENCE, the local system prepends the specified AS num as
   the last element of the sequence (put it in the left-most
   position with respect to the position of  octets in the
   protocol message) the specified number of times.
   If the act of prepending will cause an overflow in the AS_PATH
   segment (i.e.,  more than 255 ASes),
   it SHOULD prepend a new segment of type AS_SEQUENCE
   and prepend its own AS number to this new segment.

2) if the first path segment of the AS_PATH is of other than type
   AS_SEQUENCE, the local system prepends a new path segment of type
   AS_SEQUENCE to the AS_PATH, including the specified AS number in
   that segment.

3) if the AS_PATH is empty, the local system creates a path
   segment of type AS_SEQUENCE, places the specified AS number
   into that segment, and places that segment into the AS_PATH.
