Subject: ath11k failed to enqueue rx buf: -28
Content-Type: text/plain; charset=UTF-8; format=flowed

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
