TPLINK TL-WN823NV2 (RTL8192EU) support

[Fekete Zoltán <fekete.zoltan%minux.hu@localhost>]

Hi There,

I have added TL-WN823NV2 (an USB WIFI adapter) to the current kernel 
with the patch below.
The system recognises successfully, and loads the relevant firmware.
Then wpa_supplicant can connect. Leds show that the device starts to 
scan.
This repeats every 5 secs. Nice.

The problem is that wpa_supplicant can't find any network. I've a couple 
of strong signals present, so it's not an issue.

The debug message from wpa_supplicant:
urtwn0: State: DISCONNECTED -> SCANNING
urtwn0: Strting AP scan for wildcard SSID
urtwn0: Add radio work 'scan'@0xbb1d3340
urtwn0: First radio work item in the queue - schedule start immediately

EAPOL: diable timer tick

urtwn0: New scan results available (own=0 ext=0)
urtwn0: radio work 'scan'@0xbb1d3340 done in 5.353662 seconds
urtwn0: radio_work_free('scan'@0xbb1d3340: num_active_works -->0
urtwn0: No suitable nwtwork found

This repeats every 5 secs.

My question is how to solve the issue?

Thank you:
FeZ



Here is the change I've done in the usb driver:
