Where is the proper place to update the RPL HBHO

Jian Zhang

Hi all,

I am working on bring back RPL to Zephyr, which includes migrating RPL to use net_pkt API.

The old RPL implementation was using net_pkt_insert() to insert RPL HBHO header when finalizing the udp packet. However, I can see that the net_pkt_insert() was removed already.

I am not very familiar with the Zephyr network architecture. One way I can think about is to update the RPL HBHO in net_udp_create(), though not sure if this is the right way to go ahead. Please help.

Thanks and Best Regards,
