[lwip-users] dhcp --> auto-ip --> slow boot process

[Tamas Somogyi]

Hi,

My device uses dhcp+autoip option, and I noticed that finding a suitable
IP in a network where no DHCP server present takes more than one minute,
mainly because lwip spends 57 secs with retrying dhcp requests (dhcp.c).

This is a rather huge delay and I noticed that there're devices (using
different IP stacks) which gather auto-ip address more quickly (10-20
secs).

The question is that this 57 secs or number of retries is required by
some specification (RFC=?) -or- merely arbitrary numbers? 

Thanks,
Tamas
