OK. I will change the flag.
I found this with a TP-Link TL-MN8200ND, which has some variant of the RTL8188CU
chip. It transmits, but I see no evidence that the receiver is functioning at
all. The same is true for driver rtl8192cu. Only the driver from Realtek's web
site actually works.
One other problem that I have found is that the debug option on module load
seems to be ignored. So far, I've had to hard wire the flags. Once I find the
reason, I'll send a patch for that as well.
