From e18cc5b7e9ce0ac71f0e00f166ca2e2afcc3f466 Mon Sep 17 00:00:00 2001 From: Yegor Yefremov Date: Tue, 20 Feb 2018 08:47:50 +0100 Subject: DHCP: fix option 54 passing Though variable net_dhcp_server_ip was declared and used as a function parameter it was never assigned. That's why a DHCP request was sent without option 54 set. Some DHCP server for example dnsmasq didn't accept such a packet. As both offered IP address and server IP are stored in the global dhcp_result structure we don't need either net_dhcp_server_ip or OfferedIP variables and can use the addresses from dhcp_result directly.
