[Testers needed!] WiFi drivers changes

There are two I could test: athn and rsu, but neither fits iwn or bwi, and athn is not in FreeBSD src at all.

athn is in NetBSD-current and 7.0_BETA, sometimes is able to connect, but usually I get
athn0: could not load firmware (35)

Always fails with OpenBSD on USB stick (liveusb-openbsd.sourceforge.net), also fails with kernels from OpenBSD 5.5, 5.6 and 5.7 as does Ethernet (re); no success with rsu either in OpenBSD.

I see on the website that sys/dev/re was tested.

I notice, since the most recent change (2015-04-09) in sys/dev/re, that this Ethernet now works for me on new computer where it didn't before:
MSI Z77 MPOWER motherboard.

Also, the latest fix (2015-01-05) to sys/dev/usb/wlan/if_rsu.c seems to make Hiro H50191 USB WLAN adapter work again.

This success is on current amd64 and i386; no such success on FreeBSD 10.1-STABLE.

But my installed ports date to last July 26; I installed lang/gcc-aux last August 17; started updating last May 12 but hit a snag on the png update reverse dependencies, now am starting over on a new GPT partition while preserving the old (current amd64).
