#3732: arp broadcasts don't wake up laptop

 An arp request broadcast over the mesh doesn't seem to wake up the laptop.
 This means that a laptop that is in suspend will cease to be visible to
 other laptops.

 This can be tested as follows:

 1.) Set up an ad-hoc network with a couple of laptops
 2.) Start one laptop (the trigger laptop) pinging the other laptop, with
 an interval of five seconds
 3.) On the second laptop (the test laptop), enter the following script:
  count=0
  while true; do ((count=count+1)); logger -s $count; echo mem >
 /sys/power/state; done

 After a few seconds, the trigger laptop declares "Destination
 unreachable".   Waking the test laptop up manually (possibly once or twice
 until it is awake at the right time) restores the connection until arp
 times out again.

 This was discovered in exploring #2621.
