Here I moved some WEXT related for the mesh interface from wext.c
into the upcoming "mesh.c". Near the very end of this patch you
see the new iw_handler definition.
For many handlers, I simply put NULL there, but I guess
that I should do this:
a) register mesh_dev with cfg80211 as well
b) use the handlers from compat-wext.c instead
Is this right? And I guess that I connot do b) without a)
Or is it ok to do b) without a). Would then cfg80211 than always
calls into the priv->dev (for the station's struct net_device *).
I'm puzzled.
I guess that this patch --- as it is --- will leave you with a broken
mesh implementation. Or with a partially broken one, e.g. where you
can define mesh-SSID, but you cannot reduce the TX power. Not sure if
that is what we want ---- or in other words, not sure if the mesh-WEXT
handler really only needs 4 or so handler functions.
