cfg80211: provide channel to join_mesh function
Just like the AP mode patch, instead of setting the channel and then joining the mesh network, provide the channel to join the network on to the join_mesh() function. Like in AP mode, you can also give the channel to the join-mesh nl80211 command now. Unlike AP mode, it picks a default channel if none was given. As libertas uses mesh mode interfaces but has no join_mesh callback and we can't simply break it, keep some compatibility code for that case and configure the channel directly for it. In the non-libertas case, where we store the channel until join, allow setting it while the interface is down. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
