[Testers needed!] WiFi drivers changes

[Gleb Smirnoff]

  Hi!

  As part of the "opaque ifnet project" [1], we are doing some code shake
with all IEEE802.11 (read WiFi) drivers. The drivers, that provide a parent
interface for the wlan(4) interface.

  The core idea is that parent device loses its ifnet(9) structure. The
code is already complete for the stack, but only 2 drivers are converted
to new KPI: iwn(4) and bwi(4). We got 22 more drivers left. The changes
are quite mechanical, but nevertheless testing is required before committing.

So, if you run FreeBSD head and wlan(4), please sign up here as tester:

As soon as I see testers there, I will start converting more drivers.

For those who want to review the patch, or even help with converting,
you are welcome here:

Waiting for your feedback :)
