The wpa_supplicant has raised /var/run/wpa_supplicant/ndis0
wpa_supplicant tries it over and over again and restarts (unsuccessfully).

>From my preliminary analysis, this problem is due to the failure reporting the status of IEE80211 to the control file.
"op 24" probably originates from /usr/include/net80211/ieee80211_ioctl.h:
#define IEEE80211_IOC_SCAN_RESULTS 24
>How-To-Repeat:
>Fix:
Currently none.
However the problem is independent of the wpa_supplicant (I tried the port's one 0.3.8 and further 0.3.11 and the most recent one 0.6.7, which compiles (almost without trouble) under FreeBSD.
