udhcpc: account for script run time
Based on the following user report: I ran into an issue where I was seeing a long delay in the scripts called in udhcp_run_script. I was using an old version of OpenWrt (kamikaze) and a satellite modem. An NTP script was being called and the modem would sometimes take a long time to respond to the DNS lookup when it was offline. This delay started affecting my lease time. The lease that I would get from my satellite modem before it was online would be short: only 60 seconds. The delay with NTP and the modem would typically be about 18 seconds. This would cause the first DHCP renew request from dhcpc to be a little late. Under certain circumstances, I could even see the first DHCP renew to occur after the lease had expired! function old new delta udhcpc_main 2816 2837 +21 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
