[ath9k-devel] multi-vif and multi-wiphy in ath9k

[ABM Musa]

Hi,

I am trying to have both mesh and station interface in ath9k with tplink-1043nd. But I am not able to make the both interface up at the same time using ifconfig. It seems that ath9k supports multi-vif and multi-wiphy but I am not getting any good documentation about them. Following link seems to have not much info about vif 
http://wireless.kernel.org/en/users/Documentation/iw/vif

multi-wiphy commands from this post seems to be not working for me.
http://lwn.net/Articles/321690/

Can you please point me to some how-to regarding vif and multi-wiphy and is it possible to have combination of mesh, station and ap at the same time using single radio?

Thanks,
Musa

I am sure you would have change the mac-address for the virtual
interface... please get some debug message ATH_DBG_CONFIG

    ath9k: remove the virtual wiphy debugfs interface

    It does not make much sense to keep the current virtual wiphy implementation
    any longer - it adds significant complexity, has very few users and is still
    very experimental. At some point in time, it will be replaced by a proper
    implementation in mac80211.

    By making the code easier to read and maintain, removing virtual
wiphy support
    helps with fixing the remaining driver issues and adding further
improvements.

Thanks for your reply. I assigned different mac addresses to mesh and station interface and it works. However, while pinging from both mesh interface and station interface, I found many packet drop in the mesh interface. Is it the default behavior if I try to use two different active interface with a single radio? Also the station gets disassociated after sometime.

i think we should not do it. in ath9k we cannot have any other
interface when already an Ad-hoc interface is there(I have not gone
into the technical details why it should not). i think the same should
be applicable for mesh too and it may be missing in ath9k ?
