Applicable to SU/RB only.
Disable/enable the roaming feature. When enabled, the SU/RB will start
scanning for an AU/BU after about one second of not receiving beacons or data
from current AU/BU. Once it found a new AU/BU, it will also send through
the wireless network a roaming SNAP on behalf of its clients informing
other devices in the network of their new location. When disabled, it
will wait for about seven seconds before starting scanning, and it will not
send a roaming SNAP.
