The patch listed on my web page does it with minimal
fuss. Actually, I was impressed by how small it was. Notice that for
WE < 16, it uses the old iwspy support.
If you look carefully, I don't really "reclaim" the ioctl, and
it's as usual up to the driver if it wants to use the new scheme or

New wtools (24-pre4) shows : "Peers/Access Points in range".
There won't be any flags. Well, there can't be
miracles. Anything I would add would be WE-16 and later, so would not
help those older versions of WE, and starting with WE-14 we have
scanning support that has all the flags we need (cf. patch we are
In fact, if you look at the current output of iwspy with
HostAP, you have all stations and APs together without any flag. My
idea was only to move this info from iwspy to aplist.
But as you have seen, I didn't implement it in my HostAP
patch. It's because I don't know which is most important, getting only
APs or getting all stations and APs.

I'll update with your comments and re-spin.
