[GSoC Weekly Status #7] Add sta, hostap and adhoc mode to wtap wlan simulator

Hello,

This week, I read 802.1X and some of 802.11i part of <<802.11 Wireless
Networks>> to understand the mechanism of key management and cryptographic
(a little).

I also wrote some code in wtap(4) to enable hostap and sta mode, but the AP
didn't send the probe response to sta after receiving the probe request
from the sta. I want to realize what happened to the net80211, but the
whole net80211 is very huge.

So I'm going to learn dtrace(1) by reading docs in Illumos, and use
dtrace(1) to trace the function call stack when wtap(4) works.
