Comment 1 Lakshmanakumar 2023-09-19 17:29:52 UTC
I'm trying to port the ath11k driver from kernel 5.15 to kernel 5.10 for supporting the QCN9074 modules. I have also copied the firmwares from https://github.com/kvalo/ath11k-firmware/tree/master/QCN9074/hw1.0  
I could see the below logs after loading the ath11k_pci driver. But it does not proceed after the below state. Therefore the wireless network interface fails loading.
