Hostapd fails to start on a Debian stretch system against an Intel
Advanced-N 6205.
Debian package version is 2:2.4-1+deb9u1, amd64.
I've seen https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=885957
which is for the 2.6 release. I don't care about ACS in particular
(don't know if I should), just getting it to work at all would be
welcome.
