The libnl download page is a mess. The 1.1 release does exist in the
wild, but not on the libnl page. There is also a commit in the libnl
git repository called "1.1 release", although it's not tagged.
I'll try to contact the maintainer of libnl and ask to clean up all that

If you look for references to CONFIG_LIBNL20 in the sources for
wpa_supplicant and hostapd, you'll see that there is absolutely no new
functionality enabled when CONFIG_LIBNL20 is defined.

If you want to "future-proof" your distro so badly that you resort to
git snapshots of libraries, you should really use nl80211 whenever
possible. wext is in process of being obsoleted.
