Hi,
This error was brought to my attention in the kernel logs and I'm
wondering if it is of any concern:
kernel: ath11k_pci 0000:03:00.0: failed to enqueue rx buf: -28
It seems to happen every few minutes or so. I don't notice any bad
behavior associated with it per-se, but maybe its an issue of some
buffer needing to be increased in size? Does this mean a frame is being
dropped due to no room to receive it?
Hardware we are running is:
[ 4.610399] ath11k_pci 0000:03:00.0: wcn6855 hw2.1
[ 5.777030] ath11k_pci 0000:03:00.0: chip_id 0x12 chip_family 0xb
board_id 0xff soc_id 0x400c1211
[ 5.777039] ath11k_pci 0000:03:00.0: fw_version 0x1109996e
fw_build_timestamp 2023-12-19 11:11 fw_build_id
WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.36
Thanks,
James

Hi James, I was not able to reproduce this issue so wondering if you
could help reproduce and collect logs for debug. If OK please first
merge the debug patch which is available in patchwork:
https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/
Please also enable full ath11k log:
modprobe ath11k debug_mask=0xffffffff
modprobe ath11k_pci
Once enabled you should see lots of ath11k logs.

Thank you for looking at this. I'll get these changes in to test but it
may take me some time.
