How to check the NL80211_ATTR_SUPPORTED_IFTYPES attribute? about libnl HOT 2 OPEN

Usually when items in tb evaluate to None it means that the kernel/driver did not have that data to populate the dictionary with.

This library is really designed for people already familiar with the C libnl library, or more specifically, I wrote this library so I could use existing (though rare) examples of the C libnl library out on the internet.

What I would do in this case is first check if iw shows your wireless adapter does in fact support AP mode (I'm sure there's a command line option for it, been a while since I worked on this library). If it does, then I would look into its source code and try and figure out what command is sent to the kernel that produces the data you're looking for. It's possible NL80211_CMD_GET_INTERFACE doesn't cause the kernel to give you this information, maybe there's another command? Unfortunately there is no way around having to go through iw's code ;)

Sorry I can't be of much help, I haven't worked with libnl for a few months since starting my new job. I'm hoping to resume working on/with it but I'm not sure when that will be.

Ah, sorry, probably should have included that - iw does show the adapter as supporting AP mode.

    Supported interface modes:
             * IBSS
             * managed
             * AP
             * AP/VLAN
             * WDS
             * monitor
             * mesh point

Based on my understanding of nl80211 though, I thought NL80211_ATTR_SUPPORTED_IFTYPES would return the modes it does support, even if AP mode isn't one of them? I'll keep digging in iw's source as I have the time though. Thanks for the reply.
