Hi, 
 
Section 9.3 of "Transmission of IP over Infiniband" draft states that:
           " 
            [DISC] specifies the length of source/target option in
            number of 8-octets as indicated by a length of '3' above.
            Since the IPoIB link-layer address is only 20-octet long,
            two octets of zero MUST be prepended to fill the total
            option length of 24 octets.
            ".
 
However, if you look at the linux ipv6 ndisc implementation, the pad is
"appended" to the 20-byte hardware address for infiniband and not
"prepended". Could someone comment on this?
 
Thanks,
Anand.
