Yes, the driver only lets you create station interfaces, but it lets
you create several of them.
I'm not sure if that is intentional (and meaningful), or if its a bug.
Maybe you can experiment with multiple station interfaces and see if
it works in a meaningful way?

I've verified that multiple virtual interface can not work simultaneously in
STA mode. I assigned different mac address for different vifs, I can only
bring only one interface up. If I want to bring the second vif up, it always
complains "SIOCSIFFLAGS: Device or resource busy". But I'm sure that
STA vif can coexist with monitor mode vif. So I may need to add the code
login to make the watchdog only work with the vif in STA mode. Then I
can also store vif in the rtl8xxxu_priv structure if we presume it only works
for station mode. Anyone can suggest whether if this assumption is correct
or not?
