Roaming on a full mac card is quite different than soft mac and needs to be specially handled. The process starts with the CMD_ROAM event, which tells us the driver is already roamed and associated with a new AP. After this it expects the 4-way handshake to be initiated. This in itself is quite simple, the complexity comes with how this is piped into IWD. After CMD_ROAM fires its assumed that a scan result is available in the kernel, which is obtained using a newly added scan API scan_get_firmware_scan. The only special bit of this is that it does not 'schedule' a scan but simply calls GET_SCAN. This is treated special and will not be queued behind any other pending scan requests. This lets us reuse some parsing code paths in scan and initialize a scan_bss object which ultimately gets handed to station so it can update connected_bss/bss_list. For consistency station must also transition to a roaming state. Since this roam is all handled by netdev two new events were added, NETDEV_EVENT_ROAMING and NETDEV_EVENT_ROAMED. Both allow station to transition between roaming/connected states, and ROAMED provides station with the new scan_bss to replace connected_bss.
