net80211-update test

[Thomas Nikolajsen]

As I saw request for test of ath(4) on irc,
I did some test of Atheros 5212 (in my laptop).

This device has worked perfectly in DragonFly for several years,
as it also does in rpaulo's net80211-update branch from leaf.
(used docs from freebsd; not yet in branch above)

Until now only tested wlanmode sta, using wpa & dhcp;
but I have used it a few days now, with some network activity,
e.g. NFS use for updating kernel (/usr/obj).

Interesting with all the new features;
thanks for the effort, looking forward to see it committed.

I had a minor issue building kernel (WIRELESS), which was solved w/ patch below.
