Hello,
I Have a question on the same subject but not related to the bug.
I have many identical PCIe WiFi cards on the system and I need to load
a different board-2.bin on each one (1 adapter per frequency band).

So you are using multiple pcie devices at the same time in a system
with ath11k? Wondering if you are using any private patches to address
QRTR instance id clash issue [1][2].


I'm not aware of any issue of QRTR instance id clash.


To clarify: my setup is based on an NXP LS1088A SoC hosting QCN9074
PCIe cards, using the ath11k_pci driver.
The cards communicate directly over PCIe, and QRTR/QMI infrastructure
is not used or enabled in my system.
Therefore, QRTR instance ID clashes are not applicable in my context.
Maybe QRTR is only applicable for SoC AHB based integrated WiFi IPs?
And I did not use any of the patches [1] and [2].

QMI is applicable for PCIe WLAN cards as well. not sure how this works
for you without any of those patches.
