Seems to work so far for me....

I started with:

FreeBSD g1-254.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #87

Rebuilt/installed the kernel, rebooted:

FreeBSD g1-254.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #88  
r284149M/284150:1100076: Mon Jun  8 18:47:07 PDT 2015     
r...@g1-254.catwhisker.org:/common/S3/obj/usr/src/sys/CANARY  amd64

And laptop associated on channel 1.  Then I remembered that I had set
the priority of the 2.4 & 5 GHz radios the same, so I bumped the 5 GHz
one up, tolkd it to "reconnect," now it's on channel 149:

g1-254(11.0-C)[5] ifconfig wlan0

If I get a chance, I'll see if I can try it at work tomorrow -- we have a
bit higher bandwidth to the Internet there.... :-}
