No doubt there's a lot of radio traffic where I'm located.
However, every other device on my network sees my 5 Ghz ssid except for
the OpenBSD machine. I'd expect to see the ssid WIFI-NET-5G, which is on
channel 132 of an Apple Airport Extreme 802.11ac. Instead, I only see
WIFI-NET (moved to channel 7 purposefully for testing).

Trying to manually monitor channel 132, I get an error, SIOCS80211CHANNEL.

Even after a clean reboot I can't bring the interface up in monitor mode
and join anything other than channels 1-11.
