--0000000000004d837b0624ec16c2 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable The "library" is just a demonstration of how netlink events are used in communicating the state of the wifi subsystem on Linux. I would like to implement the same kernel backend for FreeBSD. The "library" uses libmnl, but I can use raw netlink sockets, it's not a problem. The problem is the lack of support (which I would like to fix) for working with nl80211 netlink on FreeBSD. I understand that you say that most of the code is already there, I will have a look at that. But I guess that the overall functionality of driving your wifi module (scan feature) from the userspace with the help of asking the kernel to do it from the kernel space is a good idea.
