For a little clarification of my test case, I'm using Peter Oh's DFS patchset from this mailing list with some memory fixes on top. It's currently WIP, so I don't posted it yet. The same issues may also surface if one uses the AP mode of wpa_supplicant, which also supports DFS. Thanks to Daniel Golle, who was asking for clarification. _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
