The current implementation loads the wifi driver only when the chip is configured, but the HAL is initialized on IWifi.start(). This seems to be wrong semantically. The driver needs to be loaded before the HAL is initialized. This may have worked previously because the driver was loaded in init.rc, but may stop working when we move to proper DLKM model in 2018. Bug: 65671875 Test: Device boots up and connects to wifi networks. Change-Id: I017d3528bf0b42a6a59af43203ecc9d0d027f60d
