Re: [PATCH v3] mac80211: Support on-channel scan option.

Did you test it?

Yes.  I added my old can-scan-one patch on top of this
so that as soon as one station is associated the rest
of the hostap-generated scans can just scan the current channel. I
then bring up 100 or so virtual stations and they all scan
and do their thing...

I also tried some manual scans on a fixed frequency.  Those
appeared to work, though I got scan results for APs on different
channels.  Does that seem right?  I can't see how my patch
would affect that sort of thing one way or another...

If you have some suggestions for other ways to test this
please let me know.

a few blank lines would be nice :)

Sure, will do.

That formatting is a bit off it seems. Or is that just my mailer?

Well, it looked OK to me..though when I replied my mailer
certainly made it look funky.  I'll re-run it through checkpatch
just in case.

Thanks,
Ben
