meaning of ioctl[SIOCSIWENCODEEXT]: Invalid argument

i am using wpa_supplicant to connect to my wlan network (Debian Wheezy)
everything works as it should but whenever wpa_supplicant is started, i get the following message:
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
it does work, but i would like to know what the system is trying to tell me with that message
anybody here who knows?

ioctl is the layer providing vector to system calls for certain device (in this case your wlan device). ioctl errors usually occur when higher application (in the userspace) misplaces or fails in some way at passing correctly arguments to the kernel vector --often caused by insufficiency of driver/module provided, or misconfiguration of internal routes. Flushing the kernel routing table will sometimes eliminate typical error report. Sometimes it will require a better driver. Rebooting may sometimes eliminate undesired err message.

Hope that helps.
