Kernel version of atlantic doesn't work with ASUS XC-100C v2 (based on AQC113CS), but this repo works

Hey there,

I am using lastest linux kernel (v6.2.2), and device initialization fails with following error:

[    7.473717] atlantic 0000:03:00.0: enabling device (0000 -> 0002)
[    7.674201] atlantic: Boot code hanged
[    7.674370] atlantic: probe of 0000:03:00.0 failed with error -110

However after loading this version of driver (after fixing compilation errors) everything works:

[92939.969084] atlantic: loading out-of-tree module taints kernel.
[92939.969240] atlantic: module verification failed: signature and/or required key missing - tainting kernel
[92939.977050] atlantic 0000:03:00.0 (unnamed net_device) (uninitialized): Hardware revision 0x0
[92940.013760] atlantic: Detect ATL2FW 1030012
[92940.019446] atlantic 0000:03:00.0 enp3s0: renamed from eth0

However this has few issues:

• Kernel is tainted
• periodic debug output

Is there any way to fix AQC113CS support in mainline Linux kernel? I am asking there because Marvell people here are also responsible for mainline linux atlantic module.

Hi Igor, thanks for the analysis, we'll check this internally. Something with timings in upstream version, or something was changed unexpectedly. The error is for hardware init - when driver can't reset the device.

@cail Thank you. Let me know if you need any more information or testing. I still have NIC laying around.
