Compiles fine on
$ uname -r
5.10.9-arch1-1
except 2 warnings:
rtl8xxxu_desc_to_mcsrate defined but not used

but its not possible to insmod the module
$ sudo insmod rtwifi.ko

did you try sudo depmod -a after copy rtwiki.ko to
/lib/modules/<<kernel e.g. 5.10.9-arch1-1>>/kernel/drivers/net/wireless/rtwifi.ko
I don't run the module from inside the modules directory.
Maybe I should run "modprobe mac80211" before insmod.
I'll try that. Thanks for pointing me into that direction.
That did the trick.
rtwifi.ko doesn't load mac80211. It must be done by hand.
Thanks.
Looks like the driver is working fine on

packet injection is working on 2.4GHz!

your injection ratio is huge - say kids what time is it?

@kimocoder no longer NETLINK dependencies.
I know, the driver is highly experimental, but I decided to add it "known as working" to hcxdumptool:
ZerBea/hcxdumptool@03c3b95
because it is working much better than the old ones!
