Have a look in src/UPDATING

 The 802.11 wireless support was redone to enable multi-bss
 operation on devices that are capable.  The underlying device
 is no longer used directly but instead wlanX devices are
 cloned with ifconfig.  This requires changes to rc.conf files.
 For example, change:
    ifconfig_ath0="WPA DHCP"
 to
    wlans_ath0=wlan0
    ifconfig_wlan0="WPA DHCP"
 see rc.conf(5) for more details.

 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta
 modules were merged into the base wlan module.  All references
 to these modules (e.g. in kernel config files) must be removed.


You need to create the wlan device from wpi0 and use that for wireless

  ifconfig wlan0 create wlandev wpi0
