[Contiki-developers] a wired question about packetbuf_attr

[Aborigines <ki...@ma...>]

Hi, everyone. I find that in contiki network-layer, data is packed up in packet_buf then it is sent. However, many attributes such hops, max_rexmits, ttl and so on are stored in packetbuf_attr. My question is that has the packetbuf_attr been sent out in some way? If so, where is the code that stands for it?
