wl18xx: WPA3 support in a mainline Linux

Yegor Yefremov

Hi,

the latest wl18xx release R8.8 was made for the 4.19.x kernel. Meanwhile, we are targeting 5.18.x. Is a new release planned?

Accoring to the changelog [1], there are a lot of patches needed to get WPA3 and MESH running. Some patches are already upstream and one [2] was first applied and then reverted. You can find the related discussion here [3]. I am still encountering this issue if I apply the patch to 5.17 kernel.

As the kernel driver for wlcore is still orphaned, could you take a look at this issue and help to upstream both MESH and WPA3 support? I am mostly interested in WPA3 support.

Hi Yegor,

As you know the latest kernel we support is the 4.19 kernel. We are discussing internally if we can build a separate release (like a R8.9, for example) to support the newer kernels, but there is no current plan or release date. Furthermore, upstreaming is not something we can support today.

Hi Sabeeh,

thanks for the quick reply. Yes, it would be great if you could make such a release. I'd be glad to test it.

Much better would be if a TI developer could take over the drivers/net/wireless/ti subsystem like it is done for the Keystone architecture [1], K3 [2], OMAP GPIO driver [3], and many other subsystems.

Yegor, thank you for your insight. I unfortunately have nothing to add or announce at this time.

All of your points are already being discussed internally.
