Subject: [mobile-ip] About Fast handover & 802.11 L2 handover

In fast handover, an MN starts handover by sending RtSolPr message
(including prospective BSSID in WLAN).
The BSSID is related to the L2 characteristics.
IEEE 802.11 uses 11 overlapped channels. (In USA, but it's not clear.)
And the MN can receive the BSSID in beacon message.
If the frequency of two AP(old AP and new AP) is different, the MN can't
receive the Beacon(also, BSSID).
It's related to the L2, but I think it's very important issue.
