yes, vendor commands API and those APIs are upstreamed. > > > Which header is this? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/nl80211-vnd-intel.h?h=v5.17-rc6 > > Usually, we want to build a version of NetworkManager that supports > most features, regardless against which kernel (headers) it was build. > Because, you should be able to upgrade your kernel and get the feature > automatically.

Ok, the header is fairly short, so I guess we can copy and fail on runtime if the kernel doesn't support? > > If this gets fetched via nl80211, then src/libnm-platform/wifi/nm- > wifi-utils-nl80211.c is the right place. > Thanks! I'll try to get some time for this. This is still sort of a side project for me, so, things can take time... _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
