Hi All,
At the outset, I do understand there is no mainstream requirement for
having virtual wireless NIC, if et all there is any, mac80211_hwsim (part
of Linux) is more than sufficient.
So this is purely an academic attempt.
In order to support following topology,
[image: qemu-wifi-topology.png]
I am implementing IEEE 802.11 softmac device based on virtio driver. I
wanted to use existing netdev trasport like socket, however due to lack of
better understanding of internals I have added new netdev (airport), which
is very similar to VDE transport implementation. On frontend side, I have
combined virtio-net and mac80211_hwsim to form frontend wireless driver.
As of now all driver are loading, and further working on correcting queue
implementation.

I have kept the repository at,

So if possible, do go through and let me know any mistakes.
Thank You.
