    wpa: Address CTRL-EVENT-SCAN-FAILED
    
    Some installations may experience CTRL-EVENT-SCAN-FAILED when
    associating to an AP. Installations that specify
    ifconfig_wlan0="WPA ... up" in rc.conf do not experience
    the problem whereas those which specify ifconfig_wlan0="WPA" without
    the "up" will experience CTRL-EVENT-SCAN_FAILED.
    
    However those that specify "up" in ifconfig_wlan0 will be able to
    reproduce this problem by service netif stop wlan0;
    service netif start wlan0. Interestingly The service netif stop/start
    problem is reproducible on the older wpa 2.9 as well.
