What is Extra: rsn_ie ?

[Timo Pannes]

Hi, 

can anybody tell me what the "Extra: rsn_ie" line in the output of "iwlist 
ath0 scanning" actually is? (anything needed for WPA2 ?)

For example, I have:

....

                    ESSID:"wellenreiter3"
                    Mode:Master
                    Frequency:2.412 GHz (Channel 1)
                    Quality=43/94  Signal level=-52 dBm  Noise level=-95 dBm
                    Encryption key:on

                    Extra:bcn_int=100                 			  
	      Extra:rsn_ie=30180100000fac020200000fac04000fac020100000fac020000


Thanks in advance,
