Pass the full apdev to the add_ap() function instead of just ifname. This allows us to handle also remote hosts while we can check apdev['hostname'], apdev['port']. This step (1) converts the cases where apdev[#]['ifname'] was used as the argument to hostapd.add_ap(). Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com>
