NM dnsmasq isolation for wifi-ap
Patch provided here has also been submitted and accepted upstream.
Side note: Though 1.12.0 should be binary compatible with previous
versions, Steam stopped working when testing 1.12.0, so I've kept
this back to 1.10.x series for the time being.
Using nmcli or nm-applet to test hotspot ap capability:
nmcli con add type wifi ifname wlan0 con-name Hostspot autoconnect yes ssid Hostspot
nmcli con modify Hostspot 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
nmcli con modify Hostspot wifi-sec.key-mgmt wpa-psk
nmcli con modify Hostspot wifi-sec.psk "veryveryhardpassword1234"
nmcli con up Hostspot
Also possible from nm-applet by creating a new connection, Setting it to
WiFi, changing the mode to Hotspot from Client, and setting the appropriate
SSID, Device, and Wi-Fi Security settings.
