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.

Nico
