Hi all,
In line 370 in nd6.c of lwip-2.1.2,
/* This is an unsolicited NA, most likely there was a LLADDR change. */
i = nd6_find_neighbor_cache_entry(&target_address);
if (i >= 0) {
if (na_hdr->flags & ND6_FLAG_OVERRIDE) {
MEMCPY(neighbor_cache[i].lladdr, lladdr_opt->addr, inp->hwaddr_len);
}
}
} else {
/* This is a solicited NA.
When dealing with unsolicited NA, only LLADDR change is deal with. (If a valid
entry is found and flags is override, then override)
However, if it is not a LLADDR change, but receiving a new LLADDR, no measure
is taken.
So when I send a message from my board to my PC, it fails when getting next hop
address (nd6_get_next_hop_addr_or_queue).
Is this an issue?
Regards,
