Subject: hostapd: Bring back support for 802.11g/a
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=64ea5031476bb7acc0a65c1b7140193d7093187e;p=ipfire-2.x.git

hostapd: Bring back support for 802.11g/a

I just have a little bit of easily accessible testing hardware in form
of USB devices which are very suitable for testing, but the one that I
found in my drawer doesn't support 802.11n.
