wcn6855 2.1 - slow download speed on any pairwise cipher except CCMP

wcn6855 2.1 - slow download speed on any pairwise cipher except CCMP

[Yaroslav Isakov]

Hello! When I tried to switch my OpenWRT router from default CCMP
pairwise cipher to any other, supported by both my router (Asus
TUF-AX6000) and my laptop (Thinkpat T14 Gen 4 AMD with WCN6855 2.1), I
saw that download dropped from 1Gbit/s to 100 MBit/s. When I changed
back to CCMP, download speed recovered back to 1Gbit/s. Upload speed
is good, though, for all ciphers - 1Gbit/s.

Initially, I thought, that issue with either router hardware, or
openwrt driver - but, I tested the same settings on another laptop -
T14 Gen3 Intel - and with Intel WIFI, both download and upload speed
was 1Gbit/s on any pairwise cipher.

This issue is 100% reproducible for me, it happens all the times I'm
switching to any pairwise cipher other than CCMP.

I'm on Linux 6.7.6, compiled from sources on Gentoo.

Here is my dmesg for ath11k:

There was another reporting of that error in this thread:

I'm not familiar with Gentoo, is there any private changes in it 
compared to upstream ath11k? If there indeed is, could you try Kalle's 
ath11k tree?

I don't think this is the same issue as reported by James there although 
same error message. For now I don't know the root cause to that message 
but it's unlikely it causes some tput issue.

Let's wait for Yasoslav verifying it on latest ath.git.

Sorry, missed the message. Gentoo kernel I'm using is very close to
upstream. I will try ath11.git, and will report there, thank you.

I checked ath.git, master branch - it has the exact same behavior as
kernel I used - 1Gbit download with CCMP, 100Mbit download with GCMP.
For me, this issue is easily reproducible, it happens 100% if I'm
switching to pairwise_cipher (and therefore, groupwise, too) other
than CCMP.

That patch is based on ath-202405301555 tag of Kalle's ath.git:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/

but I suppose it could also be applied cleanly on ToT of ath.git.

Actually, it seems that when I was copying patch from patchwork,
something went wrong. I properly downloaded it, and it applied (with
few hunks) on top of 6.9.3. After rebuilding currently running kernel,
and reloading driver - GCMP-256 finally started showing same speeds on
download as on upload! Looks like the issue is fixed, thank you a lot!

Great it can fix  your issue and thanks for testing.

Jeff, as you pointed out internally in that patch, I will repost with necessary tags added.

Great work, Baochen!

Yaroslav, would you mind providing your Tested-by tag? That way your
work is also properly attributed in the patch. This is of course
optional.
