I'll start this up with three different question, hope that's not a
problem instead of sending three different mails.
First I wonder if I should, in a production environment using the
nl80211, stick to use libnl 1.* or should I use use the git 2.0?
Second I have noticed a problem regarding reg set/get which I can't
pin down where it goes wrong (reboot resolves the issue). Following is
how I can reproduce it. Notice all the nonsense input I used. I don't
know what exactly triggers it, but the "set DU seems to be a good
candidate"

Lastly I wonder if there is any plans to extract all relevant parts of
iw to some sort of libiw? Would be helpful for us :)
