QCA6174 SDIO crashing after few days

[Adam Porter]

Firmware WLAN.RMH.4.1.1-00014-QCARMSWPZ-1

Using branch ath10k-pending-sdio-usb

I'm using this module as an access point. After a while of uptime, it
appears that all communication with the module ceases. Hostapd goes to
disassociate clients due to inactivity, then I see in the log the
resulting failures:

[94216.098042] ath10k_sdio mmc0:0001:1: failed to install key for vdev
0 peer c8:21:58:10:b3:b4: -110

It seems that I can reproduce this issue faster by connecting more
clients and pushing a lot of throughput. So perhaps this is a resource
leak in the firmware?

I do not see this issue when using qcacld.

I'm not sure how to begin debugging this issue, does anyone have any
advice or suggestions?

Thank you,
Adam
