No. I'm simply not paying attention!

% sysctl net.wlan.devices
net.wlan.devices: iwn0

Honestly, I thought I was previously using iwm(4) because I had a 
commented out line to that effect in my rc.conf ... the iwm line was 
probably a relic from me clutching at straws with regard to 
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256957>

Anyway. Sorry for the noise. Back to iwn(4) for me :-)
