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 (4) converts the cases that call hostapd.add_ap() from a helper function that got apdev[i] as an argument. Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com>
