Hi Jouni,

Sorry for the late reply.  I've been on vacations and just got back to

I see.  So we should keep all the tests backward-compatible? Seems like
a lot of extra work, but makes sense since the kernel version you're
using to run the tests is independent of the hostap version...

It can be done, but AFAICT there's currently no way to get this
information via the control interface.  To do this, I we have to export
the capa.flags information via the control API.
