Generic Info element regarding

Thanks Jouni,

	But the probe response that I got from a WPA2 AP contained a WPA IE
(0xdd). But the cipher(s) (both group & pairwise) it defined were CCMP. What
does it mean & how are we suppose to interpret it. We were expecting a WPA2
IE (0x30) with CCMP as the cipher (but there was only WPA IE (0xdd) present
in the probe respose ) . Is what we got equivalent of what we were

If you mean RSN IE with "Generic Info Element", it may have CCMP as both
the pairwise and group ciphers. Then again, it may not. IEEE 802.11i
does not require CCMP to be used and neither does it require the RSN IE
to include all the fields if default values are used.
