Progress: Hardware is already on the market, nothing left to do or could be changed for that matter.
As of 2020-08-31, linux-firmware contains firmware version 80.0, which is known to hang on the GARDENA smart gateway as long-term tests have shown (and on other machines too - Google knows). Only a cold reset resolves the problem, which is easy to do for an USB WLAN stick but very problematic (human intervention needed) on a embedded device without hardware reset capabilities for the USB device.
Therefore, all driver development and the verification is getting done with firmware version 88.2, which is not yet mainlined as of 2020-08-31, but has the mentioned problem resolved.
Currently, FW version 80.0 from vendor driver rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404 is in linux-firmware. The more recent, more stable firmware version 88.2 (contained in vendor driver v4.0.1_6911.20130308 to v4.0.9_25039.20171107) still needs to be upstreamed.
