This can be implemented like this (based on codes from our repository):

       /* RFC2292bis */
       if (np->rxopt.bits.rxhbh && opt->hop) {
               u8 *ptr = skb->nh.raw + opt->hop;
               put_cmsg(msg, SOL_IPV6, IPV6_HOPOPTS, (ptr[1]+1)<<3, ptr);
       }
       /* RFC2292 */
       if (np->rxopt.bits.rxhbh2292 && opt->hop) {
               u8 *ptr = skb->nh.raw + opt->hop;
               put_cmsg(msg, SOL_IPV6, IPV6_2292HOPOPTS, (ptr[1]+1)<<3, ptr);
       }
