when we run high bandwidth UDP traffic and we trigger a scan, the scan
state machine seems to be looping in SUSPEND->RESUME->DECISION->SUSPEND
and SET_CHANNEL seems to be never called as 'tx_empty' is never true
while running UDP traffic. fix this by settting SET_CHANNEL state when
we get into RESUME state.
Hi johannes,
i am not completely familiar with the scan state machine. used some
previous before some of your latest changes in scan state machine and
found this might help. please let me know if this does not helps
something. thank you!
