just for my curiosity - can maybe someone explain the purpose of the buffer called buffer in sys/net/network_layer/ip.c? I could not find a proper document, just that it is retrieved via “ipv6_get_buf()” from everywhere in RIOT.
It should be some receiving buffer with anything ipv6-related in it right? In that case, were does it get filled in a architectural/coding-sense?
Thanks in advance
