Hi all, question on the following snippet In the initialisation of the prev/next hop...in the cmu extensions are these targeted for adhoc stuff or is it they server any other routing purposes? (HDR_CMN(p))->next_hop_ = -2; // -1 reserved for IP_BROADCAST (HDR_CMN(p))->last_hop_ = -2; // -1 reserved for IP_BROADCAST Thanks Theo UCL/ Mobile Systems
