New release; v5.8.5 from Edimax (vendor based)

Hi there @ulli-kroll

Just an heads up we for a new driver on our hands, it looks great at first sights, but I'll go through it anyhow since I've seen vendor drivers contra Realtek releases gone wrong before.

Enjoy!

Hmm
Maybe there is the extra definition for the hidden eeprom content
I've found in rtl8812au/rtl8821au code
;-)
This is need to check for USB3 mode on rtl8812au (which can possible usb3)
and a crippled rtl8812au with only one antenna and/or bgn modes

from hal_ReadUsbType_8812AU()

		if (antenna == 1) {
			/* Config 8812AU as 1*1 mode AC mode. */
			pHalData->rf_type = RF_1T1R;
			/* UsbModeSwitch_SetUsbModeMechOn(Adapter, FALSE); */
			/* pHalData->EFUSEHidden = EFUSE_HIDDEN_812AU_VL; */
			RTW_INFO("%s(): EFUSE_HIDDEN_812AU_VL\n", __FUNCTION__);
		} else if (antenna == 2) {
			if (wmode == 3) {
				if (PROMContent[EEPROM_USB_MODE_8812] == 0x2) {
					/* RTL8812AU Normal Mode. No further action. */
					/* pHalData->EFUSEHidden = EFUSE_HIDDEN_812AU; */
					RTW_INFO("%s(): EFUSE_HIDDEN_812AU\n", __FUNCTION__);
				} else {
					/* Antenna == 2 WMODE = 3 RTL8812AU-VS 11AC + USB2.0 Mode */
					/* Driver will not support USB automatic switch */
					/* UsbModeSwitch_SetUsbModeMechOn(Adapter, FALSE); */
					/* pHalData->EFUSEHidden = EFUSE_HIDDEN_812AU_VS; */
					RTW_INFO("%s(): EFUSE_HIDDEN_8812AU_VS\n", __func__);
				}
			} else if (wmode == 2) {
				/* Antenna == 2 WMODE = 2 RTL8812AU-VN 11N only + USB2.0 Mode */
				/* UsbModeSwitch_SetUsbModeMechOn(Adapter, FALSE); */
				/* pHalData->EFUSEHidden = EFUSE_HIDDEN_812AU_VN; */
				RTW_INFO("%s(): EFUSE_HIDDEN_8812AU_VN\n", __func__);
				hal_spc->proto_cap &= ~PROTO_CAP_11AC;
			}
