Improve Wi-Fi hand-off When Wi-fi connects at L2 layer, the beacons reach and the device can maintain a connection to the access point, but the application connectivity can be flaky (due to bigger packet size exchange). We now use Watchdog to monitor the quality of the last hop on Wi-Fi using signal strength and ARP connectivity as indicators to decide if the link is good enough to switch to Wi-Fi as the uplink. ARP pings are useful for link validation but can still get through when the application traffic fails to go through and thus not best indicator real packet loss since they are tiny packets (28 bytes) and have much low chance of packet corruption than the regular data packets. Signal strength and ARP used together ends up working well in tests. The goal is to switch to Wi-Fi after validating ARP transfer and RSSI and then switching out of Wi-Fi when we hit a low signal strength threshold and waiting until the signal strength improves and validating ARP transfer.

Fix driver start/stop handling The driver start and stop events will be removed as they are now redundant (and incorrect) Move to using supplicant INTERFACE_DISABLED indication for deciding if driver has started or stopped When driver start is given, the supplicant will first switch to INTERFACE_DISABLED state and then out of it to start connecting. We should use this indication to find out driver has started When driver stop is given, the supplicant will just switch to INTERFACE_DISABLED state and this indicates driver has stopped Bug: 4550125 Change-Id: I242cda97951a733c8707c8d99cdfcc9a33b75c2d

Add new states to support wpa_supplicant 0.8 Latest supplicant introduces the INTERFACE_DISABLED state. This is entered when the interface is brought down (which is effectively done by us and tracked already through the driver stop operation) Also, added is a state for tracking authentication when supplicant acts as the SME Change-Id: I76090068d0ebba6df76f16707da559fcbd7512c5

fix network disconnection handling We should avoid network id set unless the access point is associating. Also, we should reset network connection state before sending out network change broadcast. Finally, we should reset connect mode settings when we disconnect from an access point Bug: 3424635 Change-Id: I41db5399810218abd6a77155166db5a9b1dbd22c
