Follow-up Comment #2, patch #8361 (project lwip):

This patch stores NTP server addresses in a local DHCP struct.
I think we should follow the same operations as for DNS servers:
* The DHCP server gets the offered servers and calls sntp_addserver() for each
** Pros: the DHCP module does not need to know about SNTP of the amount of
memory for servers, it just calls the add function.
** Cons: the dhcp module must know the prototype for this function and sntp.c
is not part of the lwIP tree
* The SNTP module provides a new sntp_addserver() function, similar to the
current DNS module function.
* Pros: SNTP_MAX_SERVERS is an SNTP module macro instead of NTP_MAX_SERVERS a
DHCP module macro. 

I can do the changes based on the OP uploaded patch, and submit a new patch,
if you guys agree.
