Hi,

In Rpi5 MiniPCIe with hat "52Pi Raspberry Pi 5 Mini PCIe Hat M02" I run MiniPCIe Wi-Fi cards based on the following chipsets: MT7603, MT7612 and MT7921. After installing the appropriate driver is not driver visible in lspci -k (no message: "Kernel driver in use"). I run all three cards based on the above-mentioned systems in the other device with 24.10.0-rc5 and they work properly. The issue only Raspberry Pi 5. I noticed that I need to remove wpad* to be able to install kmod-mt*.

Version: r28304-6dacba30a7
Release: 24.10.0-rc5
Target/subtarget: bcm27xx/bcm2712
Device: Raspberry Pi 5 Model B Rev 1.0

Test MT7603:

opkg install kmod-mt7603
