Qualcomm Atheros QCA9377 Wi-Fi lock up, failed to transmit packet, dropping: -12

[Patrik Arven]

Hi all

Hopefully this has been asked before, because then there might be a solution already :-)

Long story short:
================
- Connect a putty terminal trough wifi to an NXP imx6 with Qualcomm Atheros QCA9377, using ath10k_sdio 
- type "ping -f <gateway>", e.g ping -f 192.168.10.1.

The terminal window locks up and need to be killed from the client. This is observed at the serial debug console:

[86574.617400] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12
[86574.624725] ath10k_sdio mmc1:0001:1: failed to submit frame: -12
[86574.630852] ath10k_sdio mmc1:0001:1: failed to push frame: -12
[86574.774034] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12
[86574.781373] ath10k_sdio mmc1:0001:1: failed to submit frame: -12
[86574.787409] ath10k_sdio mmc1:0001:1: failed to push frame: -12

The imx6 wifi doesn't die completely, just the dropbear/ssh connection. A new putty terminal can be opened without problem.

Has anyone seen this? Is there a solution?

Where/how I got the wifi firmware:

# wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20221012.tar.gz
# tar -xzf linux-firmware-20221012.tar.gz
# ssh root@$XIP mkdir /lib/firmware/ath10k
# scp -r linux-firmware-20221012/ath10k/QCA9377 root@$XIP:/lib/firmware/ath10k

When building the kernel, I used make menuconfig.
Device drivers -> Network device support -> Wireless LAN -> 
M Atheros 802.11ac wireless cards support
M Atheros ath10k SDIO support
M Qualcomm Technologies 802.11ax chipset support
M Atheros ath11k AHB support
