Maybe we should include the list of interfaces into the GET_WIPHY command and have GET_INTERFACE never return a list? > + int (*get_channel)(struct wiphy *wiphy, int *chan, int *freq, > + enum nl80211_phymode *phymode); > + int (*set_channel)(struct wiphy *wiphy, int chan, int freq, /* XXX both?! */ > + enum nl80211_phymode *phymode); > > I don't think both are useful.

Yeah, I was hoping for feedback on this one. For one, do we even bother to return the frequency via nl80211? There's no attribute for it yet, and I don't know if this is too useful. Maybe it can be included in the channel list, so if an application really wants to know the frequency, it can look up the table using channel+phymode as key and get it. (channel list needs to be outlined next...) > In any case, looks pretty good :) Well, more or less. I messed up somewhere, a dump request for wiphys is endlessly returning me the one wiphy I have, only aborting when I kill my app. But, let's say I'm happy my box didn't explode. Guess I need to try harder. -David - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
