nrf_getaddrinfo: Only returning a single result?

[JordanYates]

Does the `nrf_getaddrinfo` API support returning multiple DNS query results?

I can confirm using the modem trace and Wireshark that the DNS server is returning multiple address.

Adding the following to `nrf91_socket_offload_getaddrinfo` only ever shows a single result:

	struct nrf_addrinfo *a = nrf_res;
	while (a) {
		printk("NEXT: %p\n", a);
		a = a->ai_next;
	}

Just wanted to let you know that I did not get to research it yet, but I should hopefully get to it in the following days.

Best regards,

Jordan,

Michal is away and I took this thread.

It seems like you are doing it right to get the list of entries and I am not sure why the list is incomplete. 

How often are you calling nrf_getaddrinfo? Or are you doing this in only one context?

My colleague said that that he will test this out soon. Will let you know if there is any additional insights from his end on Monday.

My colleague has already confirmed that he also see the same as you that even though the response from DNS server is 4 ip address, the list has only one entry. We would have to register a bug report for this. Thanks for lettings us know.
