Comment:

 This (wakeup on all broadcasts) isn't a reasonable solution; many networks
 are way to chatty for that; we can't afford to wake up every second, and
 go back to sleep.

 ARP and IPv6 NDP are similar; I don't know what the usual timeouts are.

 I suspect we'll need some sort of sane filtering at the firmware level for
 key protocols.  It also isn't clear to me that we should not forget our IP
 address after a while anyway; after a long suspend a delay for ARP and or
 NDP is reasonable, as it is quite likely the laptop has been moved anyway.
