Bug description:
[Impact]
bcmwl-kernel-source fails to build with the latest linux 6.1 in Lunar.
Moreover, with kernels >= 5.17 there's an incorrect access to struct
netdev (see LP: #1998039).
[Test case]
$ sudo apt install bcmwl-kernel-source
[Fix]
The following upstream commits have change the cfg80211 ABI in linux
>= 6.1:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=efbabc11650040c64884ff3019b88c7bcc0ceb1d
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e7a7b84e33178db4a839c5e1773247be17597c1f
Change bcmwl to properly support the new ABI changes.
Moreover, to fix the incorrect netdev access with kernels >= 5.17 we
can apply this patch
https://raw.githubusercontent.com/archlinux/svntogit-
community/master/broadcom-wl-dkms/trunk/012-linux517.patch (see LP:
#1998039 - thanks to Brett Holman for the backport and for reporting
the problem).
[Regression potential]
We may experience regressions with kernels >= 6.1 using the bcmwl-
kernel-source dkms. The code for the previous kernels remains
unchanged.
