DHCPSRV_service_release and DHCPSRV_service_decline functions are both empty, is this an omission?

In the DHCP server module dhcpsrv.c, two of the service functions are empty. Shouldn't there be some processing in there? For example, DHCPSRV_service_release should place the IP address back in the pool.

Hi Tony:

You are right, upon receipt of a DHCPRELEASE message, the server marks the network address as not allocated and retain a record of the client's initialization  parameters for possible reuse. Upon receipt of a DHCPDECLINE message, the server must mark the network address as not available and should notify the local system adminstrator of a possible configuration problem.

unfortunately, these two functions are not implemented yet, and no plan to implement it in classic MQX 4.x yet. I would suggest you implement it by yourself if it is necessary.

Hi Daniel,

Thanks for your reply. As I suspected, the functions are not implemented yet. I will see if I need those functions and implement them if need be.
