#9960: wake-on-WLAN doesn't always work

XO-1.5 os103 on B3. While pinging a system with autosuspend enabled works
OK (system suspends, wakes up soon after due to incoming ping),
interestingly it fails to wake if a ping flood is happening. I guess this
exposes some kind of timing condition with a packet arriving at the wrong
time.
To reproduce:
On 1 system as root:
ping -f <ip of XO>
XO will autosuspend and will not wake up. Resorting to a "slow" ping will
not wake the system up.
Wake up the system with a mouse movement and repeat without the -f -- the
system will suspend and resume nicely.
