<DIV><FONT size=2>The "Prism driver programmers mannual" mentions that When
setcnfRoamingMode to 2 ( I think it is realized with the command "iwpriv
wlan0 host_roaming 1, right?), the host will be interrupted with a ScanResults
Info Frame when either the PRISM MAC scans or the host initiates a scan, then
the host may issue a Join Request at that time. Therefore how to control PRISM
MAC or the host to perform the scan? Another relative question, after
debuging the driver with Printk or PDEBUG, I find that the function
"hostap_passive_scan" never can be performed, although I set the
host_roaming mode to 0,1 or 2 (I perform the debug by adding a line ---
PDEBUG(DEBUG_EXTRA, "begin passive scan \n"); just at the begin of the
function "hostap_passive_scan" , but from the dmesg result, it never has been
outputed. </FONT></DIV>
