Scan appearently is not necessary, 'ifconfig wlan0 up & sleep 0.02; ifconfig
wlan0 down' is enough. Just doing 'ifconfig wlan0 up; ifconfig wlan0 down' is
enough.
I also tested with monitor interface opened for tcpdump while doing 'ifconfig
up&down' on wlan0 and still triggered the issue. Then turning wlan0 up resulted
monitor interface only receiving probe requests from nearby devices.
I am in the middle of a long-term test of rtl8192ce, which keeps me from running
tests of rtl8192cu, but I noticed something strange. Does the attached patch
help? It is compile tested.
