Firmwares may not provide all monitor mode features in the "cap" iovar.
For those this fallback mechanism uses "sta_monitor" iovar. If firmware
is compiled with stamon, this iovar will fail with BCME_NOTUP; Otherwise
it fails with BCME_UNSUPPORTED.
It's probably not the first time ever, but it appears your research
(theory) doesn't match my experience (practice) ;) I'm afraid you
missed some important check when analyzing firmware code.
It was not all theory ;-) but apparently I did not cover all bases. I
only checked with 4366c0 (actually with 43664 aka 4366E) on the release
branch I am working on.
I've just tested all firmwares I got (for 43602a1, 4366b1 and 4366c0)
and all of them return -4 (BCME_NOTUP) for "sta_monitor" when
firmware/interface is down. It appears this test requires bringing
firmware/interface up to make it reliable. Apparently even firmwares
*without* sta_monitor return -4 (BCME_NOTUP) when firmware/interface
is down.
That is crap. So back to the drawing board. Thanks for keeping the taps
on this.
