I'm not sure this is a good idea? What if this collides with hostapd updating the beacon? Or what if hostapd wants to change the color later for some reason? Or if we get a concurrent CSA? Especially that last point seems a bit tricky, if we have it both in hostapd at least we can decide not to do them in parallel? OTOH, if we do this one in the kernel it might be a bit easier to do them in parallel (at the expense of the more complex code), but is that desirable? Will clients understand it? johannes _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
