Re: [Aironet] Linux, Aironet, and RFMON mode

[Benjamin R. <br...@al...>]

I am surprised Etherreal can handle 802.11 since the kernel support for
802.11 packets seems rather unused.  I'm in the same boat as Javier:  it is
easy to put in, but will anyone use it?  (When I say anyone, I mean will
any applications support it?)

I've thought of adding that functionality to the driver. It shouldn't be
really hard. I haven't done it because I didn't see any application for
it.
