Which Debian Stretch package provides firmware for the Realtek RTL8814U chip? In particular, the Comfast CF-917AC 1750Mbps USB3 adapter: https://www.amazon.com/dp/B01B75MHR0 .
Kali Linux supports the RTL8814 natively: https://www.kali.org/news/kali-linux-20171-release/ . Further, there are some clues here: https://bugs.kali.org/view.php?id=3260 https://github.com/diederikdehaas/rtl8812AU https://github.com/astsam/rtl8812au https://github.com/lwfinger/rtlwifi_new But, I'm looking for an "official" Debian firmware package. I wasn't able to find the rt8814 mentioned here: https://www.debian.org/distrib/packages nor here: http://linux-wless.passys.nl/query_chipset.php?chipset=Realtek nor here: https://wireless.wiki.kernel.org/en/users/drivers
