[Olsr-dev] hna and tc set

[Airton Ishimori]

In hna_set.c there are bellow code lines. Why has that add 8? Would be
netmask size?

     if (olsr_msgsize < 8 + olsr_cnf->ipsize) {
    #ifndef WIN32
        OLSR_PRINTF(1, "HNA message size %d too small (at least %zu)!\n",
olsr_msgsize,
                    8 + olsr_cnf->ipsize);
    #endif
        return false;
      }

and in the tc_set.c has bellow code lines. What is lower_border and
upper_border?

    /* Get borders */
      pkt_get_u8(&curr, &lower_border);
      pkt_get_u8(&curr, &upper_border);
