[ns] question on cmu initialisations

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
