change 19.04.2022
I get the wave300 wlan running on Speedport W921v, but with old driver stack, only 21.02 branch, only 5GHz, AP-mode only, stability not testet and with an extra modified old hostapd program
It ist for testing only in the moment.
The Interface will only control over the init.d script, which is inside the firmware package.
The packahge feed is here: https://github.com/Plonkbong/openwrt-feeds-wave300
Build the following packages aigainst the SDK from Release 21.02.2 builddate: 27.03.2022
wave300-garlett -> the kernel module
fw-wave300-spw921v -> the firmware file + init script do a look inside the /etc/init.d/wave300-spw921v script
hostapd-devel-mtlk-benjaminlevine -> the hostapd program (called: mtlk-hostapd)
thanks for the people from this thread: Support for WAVE 300 Wi-Fi chip
