Configure WAN Interface Boot Delay

DHCP server responds within just a few milliseconds, but boot up hangs on configure WAN interface for 20+ seconds. The interface is active and responding to traffic during this time of delay with no firewall rules activated. Totally open system.

Same config on 2.3.3 i386 continues right on through without delay.

I have seen this as well, though I haven't yet attempted to narrow it down.

At least on my box, I've narrowed it down to the call to dhclient at source:src/etc/inc/

Only suspicious thing in the dhclient error output is:

igb1: no link ...... got link

If I kill it and run it manually, it works immediately. Only at bootup does it appear to hesitate. From the message, I'd guess that the physical link isn't showing as up right away, but there is no related console message about the link coming up at the time, either.

I was seeing this issue on all my test VMs too but on recent snapshots it seems to be OK, probably some change have fixed it. Leaving it in feedback state for now to hear from more people

I'm also not seeing a long delay any more. I suspect the fix for #7042 might have also fixed this. The previous delay could have been waiting on the failing DNS request from that problem.
