OK, this is weird.  I did not use your change to dhclient.
However, I did use Matthew Dodd's change to if_xl.c.
I rebuilt the kernel, powered down, rebooted, and things seem
to work better.

Before Matthew's patch, ifconfig xl0 would never print out
"status:"

Now, ifconfig xl0, *always* prints out:
"status: no carrier"

even if I do have carrier.

If I run dhclient (without your patch, but with debugging), I get:

Now, if I add the following lines to /etc/dhclient.conf (I've never
had to modify this file before):
 
interface "xl0" {
   media "autoselect";
}

I then get the following from dhclient:

Note, now that I am online, if I do ifconfig xl0, I get the following:

xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=8<VLAN_MTU>
	inet6 fe80::260:97ff:fe72:adf0%xl0 prefixlen 64 scopeid 0x2 
	inet 66.31.45.197 netmask 0xfffff800 broadcast 255.255.255.255
	ether 00:60:97:72:ad:f0
	media: Ethernet 10baseT/UTP (10baseT/UTP <half-duplex>)
	status: no carrier


So it looks like maybe there is a problem with the xl driver?
(Note I am running with Matthew Dodd's patch).

It would be nice to get this to work so that I don't have to
edit /etc/dhclient.conf, since I never had to do it before.
