I just checked wl.mk (it's an open source file) and found following line: WLFILES_SRC_HI += src/wl/sys/wlc_stamon.c not guarded by any ifeq. It appears wlc_stamon.c is always being compiled in. Are you 100% sure that wlc_stamon.c depends & uses radiotap? Are you sure it's impossible to include stamon support without radiotap support? I'm asking because we're going to check "sta_monitor" iovar to find out if radiotap support is included. I'd like to be sure it's 100% reliable.
