The problem is that there isn't a direct mapping between what's
visible with the "tail" command and what firmware returns for the
"cap" iovar. Just to be sure I bumped #define MAX_CAPS_BUFFER_SIZE to
1024. Firmware that has "stamon" when checked with "tail" command
doesn't report "stamon" over "cap" iovar. So I can't detect if
firmware was compiled with WL_MONITOR and WL_RADIOTAP using "cap"
iovar.
