Hi,

if ((has_directlink_flag) && (if_incoming->addr.sin_addr.s_addr ==
bat_packet->orig) && (bat_packet->seqno - if_incoming->out.seqno + 2
== 0)) {

					debug_output(4, "count own bcast (is_my_orig): old = %i, 

",

orig_neigh_node->bcast_own_sum[if_incoming->if_num]);

					bit_mark((TYPE_OF_WORD
*)&(orig_neigh_node->bcast_own[if_incoming->if_num * num_words]), 0);
					orig_neigh_node->bcast_own_sum[if_incoming->if_num] =
bit_packet_count((TYPE_OF_WORD
*)&(orig_neigh_node->bcast_own[if_incoming->if_num * num_words]));

					debug_output(4, "new = %i \n",
orig_neigh_node->bcast_own_sum[if_incoming->if_num]);

				}

you may want to look at the corresponding kernel code because it is way 
cleaner and easier to understand.

Cheers,
Marek
