* include/NetworkManager.h - Kill NMNetworkType; AP types don't matter any more * src/NetworkManagerAPList.c src/NetworkManagerAPList.h src/Makefile.am - Kill; NMAccessPointList has outlived it's usefulness * src/NetworkManagerAP.c src/NetworkManagerAP.h - (match_cipher, security_compatible, nm_ap_check_compatible): new functions; check if an NMConnection object is compatible with the settings of this AP - (freq_to_channel, channel_to_freq): utility functions for channel <-> frequency conversion * src/nm-device.c src/nm-device.h - (nm_device_get_best_connection): pass the specific object around (which might be the object path of a specific AP to connect to). The get_best_connection() call should populate this on return if needed (wireless does). * src/nm-device-802-3-ethernet.c - (real_get_best_connection): handle specific_object argument * src/NetworkManager.c src/NetworkManagerMain.h - Remove unused includes * src/nm-device-802-11-wireless.c src/nm-device-802-11-wireless.h - Convert the ap_list into a GSList from an NMAccessPointList - No need for caching the 'activation_ap' since this is now determined from the specific_object of the activation request, which is populated from the get_best_connection() call or from a user request - (nm_device_802_11_wireless_update_bssid): fix warning - (get_wireless_capabilities): fix error message format arguments - (nm_device_802_11_wireless_copy_allowed_to_dev_list): remove, unused - (find_best_connection, real_get_best_connection): implement - (ap_list_get_ap_by_ssid, nm_device_802_11_wireless_ap_list_print): move here from NetworkManagerAPList - (ap_need_secrets): remove; moved to nm-connection.c where it belongs - (real_act_stage1_prepare): just ensure an AP exists, connection is already verified earlier - (real_act_stage2_config): use nm_connection_need_secrets() * src/NetworkManagerPolicy.c - (nm_policy_auto_get_best_device): handle specific objects - (create_connection): remove; automatic connection creation functionality is handled by the Connection objects - (nm_policy_device_change_check): handle specific_object * libnm-util/nm-connection.c - (wireless_sec_need_secrets, nm_connection_need_secrets): implement git-svn-id: http://svn-archive.gnome.org/svn/NetworkManager/trunk@2778 4912f4e0-d625-0410-9fb7-b9a5a253dbdc
