Fix compile error on linux 6.6

[comphilip]

Linux 6.6 has several minor changes which result in compile errors and compile warnings.

Please merge this. I can't build exanic on ubuntu 22.04 without it.

By the way, I have kernel 6.5.0-26-generic #26~22.04.1-Ubuntu and I still face the same compilation errors, so probably the version checks in this patch should be downgraded to kernel 6.5 (or earlier).

[pdavydov108]

oh, I'm afraid it's not enough. It doesn't compile if I don't change all the checks to kernel 6.5 or earlier.

@pdavydov108 I only tested LTS stable kernel version only (6.1 switch to 6.6), for stable and mainline kernel version, I have little of time to test. I am not familiar change logs of kernel. I just search kernel commits in https://github.com/torvalds/linux to found and lucky got the answer.

It is welcome for you to modify the version condition and test it on kernel 6.5.

I can fix and test across the different versions and get all the various bits sorted out. It’ll just take me a bit since I’m traveling at the moment.

The version check should be for 6.4.0 not 6.6.0 in some places.
