This means that we got an invalid TX rate, notably an HE rate was
requested/configured on a MAC configuration that didn't have HE.
I think I saw some patches in this area (configuring the MAC to be HE)
fly by internally recently, but not sure... Luca probably knows.
Ah okay. This was reported on 5.4 kernel, do you think is it worth
trying on latest iwlwifi-next tree? Or as you are referring to the internal tree
the issue is present in the latest as well?
Hi Luca,
Can you please take a look? Any help is appreciated.
Hi,
There have been some new patches in this area, but after a quick look I
didn't find anything specific that jumps out. I'll take a closer look
and let you know if I find anything.
In the meantime, you could try our public backport-iwlwifi tree, where
most of the internal tree is published:
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git/
This is an out-of-tree driver, based on the linux-backports project.
You could try the core56 branch, for instance, or even master and
check if the problem is still there. If not, we can try to look for
the patch that fixes it and push it to stable.
I'm curious if anyone is interested in helping to maintain a non-backports version of this,
something like how I did the ath10k-ct driver. I'd like to use this driver, but
don't want to use the rest of the backports funk.
Thanks,
Ben
