Whoa!

while I get the "ifconfig wlan0 list scan" output (although some stuff
is wrong as the S:N values are very similar to each other),
the "ifconfig -v wlan0 list scan" variant crashes the utility but
not the kernel.

(the packets scanned by the 802.11 monitor mode on Linux sent privately)

True to the spirit of yak shaving, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=298382 is found and fixed.
