Currently mac80211 does not support WDS and DFS with channel context
drivers. So advertise these features only when the driver is not
supporting channel context and modparam "use_chanctx" is introduced
for preparing channel context support in ath9k.

Shouldn't this be ARRAY_SIZE(wds_limits)?

Julian,

Right now mcc support is not implemented in ath9k and am working on that.
Once all channel context callbacks are added, iface_combinations will
refer to right interface set.

I was referring to the n_iface_combinations = 1 line which doesn't
seem to match the size of if_comb.

Of course there's probably something subtle I'm missing =)
