Currently the dynamic ps timer is restarted for all non-multicast rx data
frames. Congested networks have lots of broadcast traffic, which will cause
the power save to remain disabled for much of the time, which causes trouble
for battery-powered devices.
Fix this by preventing rx broadcast data frames from restarting the
dynamic ps timer.
