I am not familiar with this driver.
But looks like for any other country except for WORLD mode
it is disabling both beacon and country_ie hints. But for any
other country these hints are enabled.
may be you can try the below patch (not based on 4.1 so you might have to port)
for your case disabling country_ie for all regulatory domains.
