Hey devs!

In both of these versions, the update of the carrier flag seems
to be "different" than before (linux-2.6.34-08528-gb3f2f6c):

wlan0 (iwlagn) does not recognize it's disconnected
and eth0 (e1000e) does only react correctly after I restarted
dhcpcd (isc):

[11:20] kr:pm# dhcpcd eth0 
dhcpcd: version 5.2.2 starting
dhcpcd: eth0: waiting for carrier
^Cdhcpcd: received SIGINT, stopping
dhcpcd: eth0: removing interface
[11:20] kr:pm# dhcpcd eth0
dhcpcd: version 5.2.2 starting
dhcpcd: eth0: broadcasting for a lease
dhcpcd: eth0: offered 129.132.102.115 from 129.132.65.12
dhcpcd: eth0: ignoring offer of 129.132.102.115 from 129.132.57.97
dhcpcd: eth0: acknowledged 129.132.102.115 from 129.132.65.12
dhcpcd: eth0: checking for 129.132.102.115
dhcpcd: eth0: leased 129.132.102.115 for 86400 seconds
dhcpcd: forking to background

It's known that iwlagn has problems after suspend/resume,
but new is that both nics do not notify dhcpcd that the link
has gone. I'm not sure what / where broke here, just see that
dhcpcd noticed it before and now doesn't anymore.

Had the same dhcpcd issue here both with e1000e and bnx2 and definitely
after the .35 merge window. dhclient doesn't seem affected.
